The property "dtype:orderIndex" is an annotation property to specify a position that some value or structure will have. One use is to specify the place that a resource has in a sequence. One use is on property occurrences in class axioms. Here "vaem:orderIndex" is placed on a restriction to specify how that property may be transformed into a representation where ordering has some importance, for example, in XML Schema sequences.

This property relates a system of units with a unit of measure that is either a) defined by the system, or b) accepted for use by the system and is convertible to a unit of equivalent dimension that is defined by the system. Systems of units may distinguish between base and derived units. Base units are the units which measure the base quantities for the corresponding system of quantities. The base units are used to define units for all other quantities as products of powers of the base units. Such units are called derived units for the system.

is base quantity kind of system
This property relates a unit of measure to the system of units in which it is defined as a base unit for the system. The base units of a system are used to define the derived units of the system by expressing the derived units as products of the base units raised to a rational power.
is base unit of system
A coherent unit of measurement for a unit system is a defined unit that may be expressed as a product of powers of the system's base units with the proportionality factor of one. A system of units is coherent with respect to a system of quantities and equations if the system of units is chosen in such a way that the equations between numerical values have exactly the same form (including the numerical factors) as the corresponding equations between the quantities. For example, the $newton$ and the $joule$. These two are, respectively, the force that causes one kilogram to be accelerated at 1 metre per (1) second per (1) second, and the work done by 1 newton acting over 1 metre. Being coherent refers to this consistent use of 1. In the old c.g.s. system , with its base units the centimetre and the gram, the corresponding coherent units were the dyne and the erg, respectively the force that causes 1 gram to be accelerated at 1 centimetre per (1) second per (1) second, and the work done by 1 dyne acting over 1 centimetre. So $1 newton = 10^5 dyne$, $1 joule = 10^7 erg$, making each of the four compatible in a decimal sense within its respective other system, but not coherent therein.

The property "dtype:defaultValue" is a general property for specifying a value in situations where none is specified, or can be determined. In some cases of use, this property could have a scalar value and in other cases may need to refer to a first class concept that holds a "value object". For this reason, the type of this property is set as "rdf:Property" and the property is rangeless.

The property "vaem:hasAspect" is used to distinguish among sets of features of a domain or subject area. The term is borrowed from "aspect-oriented" programming, where it is used to separate concerns. An ontology may be characterized by this dimension so as to parition features that are orthogonal. For example, in a systems ontology we can distinguish aspects for "structure", "function", "behavior" and "interface". The property is an "rdf:Property" to allow both scalar and object values
has aspect
The property "vaem:hasDimension" is used categorize an ontology. In VAEM, the property is used to characterize an ontology graph.
has dimension
The property "vaem:hasDiscipline" is used to indicate relevance of a set of resources, or a resource itself, to a specific discipline of work or study. Examples of disciplines in the engineering domain are electrical engineering, mechanical engineering and, in the financial domain, risk assessment, investment analysis. In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values
has discipline
The property "vaem:hasDomain" is used to specify how a set of resources, or an individual resource is grounded in a domain, that is, a subject area of interest. Examples of domains are "enterprise", "process", "organization" and "system". In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values
has domain
The property "lms:hasGraphRole" is used to characterize how a resource participates in an ontology set. The property is used to specify the role that a graph plays, for example, an ontology graph can be a schema, vocabulary, dataset, script, or ruleset
has graph role

The property "vaem:hasViewpoint" is used to denote how a set of resources, or an individual resource, is relevant to a context of use. The term "viewpoint" is adopted from the ISO RM-ODP specifications and its more recent use in enterprise architecture descriptions. In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values
has viewpoint
To express how statements in a model can be reifiable, this property is used to explicitly associate a property with a user-defined sub-class of "rdf:Statement". A recommended way of using this is to declare the properties that share the same reification constructs as sub-properties of a parent property that carries the "vaem:reifiableBy" property. The parent property should be of type "rdf:Property" so that it can have both datatype and object properties as sub-properties. By this means use and transformations of a model can be understood through a fully specified metamodel. "vaem:reifiableBy" is rangeless in order to comply with OWL DL semantics. Its range would have been rdfs:Class in order to refer to "rdf:Statement" sub-classes

has broader match
skos:broadMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes.
Broader concepts are typically rendered as parents in a concept hierarchy (tree).
has broader
Relates a concept to a concept that is more general in meaning.
By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources.
has broader transitive
skos:broaderTransitive is a transitive superproperty of skos:broader.
By convention, skos:broaderTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application.
close match
has close match
skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications. In order to avoid the possibility of "compound errors" when combining mappings across more than two concept schemes, skos:closeMatch is not declared to be a transitive property.
has top concept
Relates, by convention, a concept scheme to a concept which is topmost in the broader/narrower concept hierarchies for that scheme, providing an entry point to these hierarchies.
is in scheme
Relates a resource (for example a concept) to a concept scheme in which it is included.
A concept may be a member of more than one concept scheme.
These concept mapping relations mirror semantic relations, and the data model defined below is similar (with the exception of skos:exactMatch) to the data model defined for semantic relations. A distinct vocabulary is provided for concept mapping relations, to provide a convenient way to differentiate links within a concept scheme from links between concept schemes. However, this pattern of usage is not a formal requirement of the SKOS data model, and relies on informal definitions of best practice.
is in mapping relation with
Relates two concepts coming, by convention, from different schemes, and that have comparable meanings
has member
Relates a collection to one of its members.
For any resource, every item in the list given as the value of the
skos:memberList property is also a value of the skos:member property.
has member list
Relates an ordered collection to the RDF list containing its members.
has narrower match
skos:narrowMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes.
Narrower concepts are typically rendered as children in a concept hierarchy (tree).
has narrower
Relates a concept to a concept that is more specific in meaning.
By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources.
has narrower transitive
skos:narrowerTransitive is a transitive superproperty of skos:narrower.
By convention, skos:narrowerTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application.
skos:related is disjoint with skos:broaderTransitive
has related
Relates a concept to a concept with which there is an associative semantic relationship.
has related match
skos:relatedMatch is used to state an associative mapping link between two conceptual resources in different concept schemes.
is in semantic relation with
Links a concept to a concept related by meaning.
This property should not be used directly, but as a super-property for all properties denoting a relationship of meaning between concepts.
is top concept in scheme
Relates a concept to the concept scheme that it is a top level concept of.
Indicates whether a component property is required (true) or optional (false) in the context of a DSD. Only applicable
to components correspond to an attribute. Defaults to false (optional).
component required
indicates a priority order for the components of sets with this structure, used to guide presentations - lower order numbers come before higher numbers, un-numbered components come last

An abbreviation for a unit is a short ASCII string that is used in place of the full name for the unit in contexts where non-ASCII characters would be problematic, or where using the abbreviation will enhance readability. When a power of abase unit needs to be expressed, such as squares this can be done using abbreviations rather than symbols. For example, <em>sq ft</em> means <em>square foot</em>, and <em>cu ft</em> means <em>cubic foot</em>.

The currency exponent indicates the number of decimal places between a major currency unit and its minor currency unit. For example, the US dollar is the major currency unit of the United States, and the US cent is the minor currency unit. Since one cent is 1/100 of a dollar, the US dollar has a currency exponent of 2. However, the Japanese Yen has no minor currency units, so the yen has a currency exponent of 0.

The "qudt:id" is an identifier string that uniquely identifies a QUDT concept. The identifier is constructed using a prefix. For example, units are coded using the pattern: "UCCCENNNN", where "CCC" is a numeric code or a category and "NNNN" is a digit string for a member element of that category. For scaled units there may be an addition field that has the format "QNN" where "NN" is a digit string representing an exponent power, and "Q" is a qualifier that indicates with the code "P" that the power is a positive decimal exponent, or the code "N" for a negative decimal exponent, or the code "B" for binary positive exponents.

The property "dtype:order" provides a means to specify a precedence. One use of order is in specifying ordered enumerations such as "voag:ConfidentialityLevel". A similar property, but with an important type difference, is "vaem:orderIndex". This is for use on property occurrences in class axioms where it can be placed on a restriction to specify how that property may be transformed into other representations where ordering has some importance, for example, in XML Schema sequences. Whereas "vaem:order" is a datatype property, "vaem:orderIndex" is an annotation property.

The property "vaem:name" is intended for general use. In many cases "rdfs:label" could be used give names to resources. In the case where compliance with a specific naming rule is needed, "vaem:name" allows a resource to carry a name that is used in more specific contexts.
name
The property "vaem:namespace" is the onotlogy URI with which a graph is primarily associated. The intent is to allow multiple graphs to define statements for resources in the same Ontology namespace. For example, a foundation level graph with the base URI of "http://www.somesite.com/1.0/schema/OurOntology" may define general concepts for "OurOntology". Another graph with the base URI "http://www.somesite.com/1.0/schema/level2/OurOntology" may add more specific details to the same "OurOntology". Each of these two graphs would carry the same value for "vaem:namespace", that is, "http://www.somesite.com/schema/OurOntology". In other words, an ontology URI is the URI associated with the resources of a controlled namespace. On the other hand the graph URIs (the base URIs) identify the graphs that hold resources that make up an ontology
namespace
The property "vaem:namespacePrefix" specifes a short handle or label for the URI of an Ontology. Multiple graphs can define statements for resources in the same Ontololgy namespace. For example, a foundation level graph with the base URI of "http://www.somesite.com/1.0/schema/OurOntology" may define general concepts for "OurOntology". Another graph with the base URI "http://www.somesite.com/1.0/schema/level2/OurOntology" may add more specific details to the same "OurOntology". Each of these two graphs would carry the same value for "vaem:namespacePrefix", for this example, perhaps, "ourOntology"

A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time. It can be contrasted with a mathematical constant, which is a fixed numerical value but does not directly involve any physical measurement. There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, Newton's gravitational constant G, Planck's constant h, the electric permittivity of free space ε0, and the elementary charge e. Physical constants can take many dimensional forms, or may be dimensionless depending on the system of quantities and units used.

qudt:SystemOfQuantities
A system of quantity kinds is a set of one or more quantity kinds together with a set of zero or more algebraic equations that define relationships between quantity kinds in the set. In the physical sciences, the equations relating quantity kinds are typically physical laws and definitional relations, and constants of proportionality. Examples include Newton’s First Law of Motion, Coulomb’s Law, and the definition of velocity as the instantaneous change in position. In almost all cases, the system identifies a subset of base quantity kinds. The base set is chosen so that all other quantity kinds of interest can be derived from the base quantity kinds and the algebraic equations. If the unit system is explicitly associated with a quantity kind system, then the unit system must define at least one unit for each quantity kind. From a scientific point of view, the division of quantities into base quantities and derived quantities is a matter of convention.

vaem:Aspect
Aspect is used to distinguish among sets of features of a domain or subject area. The term is borrowed from "aspect-oriented" programming, where it is used to separate concerns. An ontology may be characterized by this dimension so as to parition features that are orthogonal. For example, in a systems ontology there may be aspects for "structure", "function", "behavior" and "interface" or "interoperability". A viewpoint can be distinguished by "aspects". For example the "information viewpoint" of an application can be partitioned into separate graphs for the "security", "operational" and"data retention" aspects.

vaem:Dimension
A dimension identifies a separation of concens that serves as a way to categorize an ontology graph. In VAEM, the notion of "Dimension" is partitioned into "Aspect", "Discipline", "Domain" and "Viewpoint".
Domain
vaem:Discipline
A discipline is a specific area of work or study. Examples of disciplines in the engineering domain are electrical engineering, mechanical engineering and, in the financial domain, risk assessment, investment analysis. In VAEM, discipline is used as a dimension for characterizing an ontology graph
Discipline Dimension
vaem:Domain
A domain is a subject area of interest. Examples of domains are "enterprise", "process", "organization" and "system". In VAEM, "Domain" is used as a dimension for characterizing an ontology graph

vaem:Viewpoint
Viewpoint is used to denote how a set of resources, or an individual resource, is relevant to a context of use. The term "viewpoint" is adopted from the ISO RM-ODP specifications and its more recent use in enterprise architecture descriptions. The RM-ODP introducesd the concept of viewpoint to describe a system from a particular set of concerns. RM-ODP defines five viewpoints. Together they provide a complete description of a system: enterprise viewpoint, information viewpoint, computational viewpoint, engineering viewpoint, and technology viewpoint. In VAEM, "Viewpoint" is used as a dimension for characterizing an ontology graph. The viewpoints of an ontology may not always correpsond directly to those of a system but the idea of describing a subject area of interest from distinct viewpoints is still relevant. A viewpoint can be further distinguished by "aspects". For example the "information viewpoint" of an application can be partitioned into separate graphs for the "security", "operational" and"data retention" aspects.

Vegetation vitality. NDVI correlates with the amount of leaf area (LAI) of active, healthy, green vegetation. Advantage: The most widely used vegetation index. Disadvantage: It saturates at high LAI levels and therefore shows limited variation in dense fields with high biomass. It minimizes topographic effects. Negative values of NDVI (values approaching -1) typically correspond to open water. Values around zero (-0.1 to 0.1) generally correspond to bare soil, barren areas of rock, sand, or snow. Low, positive values represent low or sparse vegetation (approximately 0.2 to 0.4), while high values indicate dense vegetation (values approaching 1).

The ontology "dtype" provides a specification of simple data types such as enumerations and codelists. These are needed in support of the conversion of XML Schemas and UML Models to OWL. The purpose of "dtype" is to provide a foundation for expressing rich data types. These data types are typically needed when dealing with OWL representations of data structures derived from XML Schema.

<p class="lm-para">The QUDT, or "Quantity, Unit, Dimension and Type" schema defines the base classes properties, and restrictions used for modeling physical quantities, units of measure, and their dimensions in various measurement systems. The goal of the QUDT ontology is to provide a unified model of, measurable quantities, units for measuring different kinds of quantities, the numerical values of quantities in different units of measure and the data structures and data types used to store and manipulate these objects in software.</p>
<p class="lm-para">Except for unit prefixes, all units are specified in separate vocabularies. Descriptions are provided in both HTML and LaTeX formats. A quantity is a measure of an observable phenomenon, that, when associated with something, becomes a property of that thing; a particular object, event, or physical system. </p>
<p class="lm-para">A quantity has meaning in the context of a measurement (i.e. the thing measured, the measured value, the accuracy of measurement, etc.) whereas the underlying quantity kind is independent of any particular measurement. Thus, length is a quantity kind while the height of a rocket is a specific quantity of length; its magnitude that may be expressed in meters, feet, inches, etc. Or, as stated at Wikipedia, in the language of measurement, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum, energy, and weight, and units are used to describe their measure. Many of these quantities are related to each other by various physical laws, and as a result the units of some of the quantities can be expressed as products (or ratios) of powers of other units (e.g., momentum is mass times velocity and velocity is measured in distance divided by time).</p>

qudt:Dimension
A "dimension" is a relationship between a quantity system, a quantity kind of that system, and one or more dimension vectors. The dimension of a quantity can be expressed as a product of basic dimension vectors for each of the system's base quantiy kinds, such as mass, length and time. The vector's magnitude determines the exponent of the base dimension for the referenced quantity kind.
Dimension
qudt:DimensionVector
<p>A dimension vector is an association between a quantity kind and a rational number. The quantity kind serves as the basis vector in an abstract vector space, and the rational number is the vector magnitude. The abstract vector space is determined by the chosen set of base quantity kinds for a quantity system.</p>
<p>Dimension Vector is now deprecated, superceded by <em>qudt:QuaniityDimensionVector</em></p>
Dimension Vector
true
qudt:EnumeratedValue
<p>This class is for all enumerated and/or coded values. For example, it contains the dimension objects that are the basis elements in some abstract vector space associated with a quantity kind system. Another use is for the base dimensions for quantity systems. Each quantity kind system that defines a base set has a corresponding ordered enumeration whose elements are the dimension objects for the base quantity kinds. The order of the dimensions in the enumeration determines the canonical order of the basis elements in the corresponding abstract vector space.</p>
<p>An enumeration is a set of literals from which a single value is selected. Each literal can have a tag as an integer within a standard encoding appropriate to the range of integer values. Consistency of enumeration types will allow them, and the enumerated values, to be referred to unambiguously either through symbolic name or encoding. Enumerated values are also controlled vocabularies and as such need to be standardized. Without this consistency enumeration literals can be stated differently and result in data conflicts and misinterpretations.</p>
<p>The tags are a set of positive whole numbers, not necessarily contiguous and having no numerical significance, each corresponding to the associated literal identifier. An order attribute can also be given on the enumeration elements. An enumeration can itself be a member of an enumeration. This allows enumerations to be enumerated in a selection. Enumerations are also subclasses of Scalar Datatype. This allows them to be used as the reference of a datatype specification.</p>

qudt:IntervalScale
<p>The interval type allows for the degree of difference between items, but not the ratio between them. Examples include temperature with the Celsius scale, which has two defined points (the freezing and boiling point of water at specific conditions) and then separated into 100 intervals, date when measured from an arbitrary epoch (such as AD), percentage such as a percentage return on a stock,[16] location in Cartesian coordinates, and direction measured in degrees from true or magnetic north. Ratios are not meaningful since 20 °C cannot be said to be "twice as hot" as 10 °C, nor can multiplication/division be carried out between any two dates directly. However, ratios of differences can be expressed; for example, one difference can be twice another. Interval type variables are sometimes also called "scaled variables", but the formal mathematical term is an affine space (in this case an affine line).</p>

qudt:NominalScale
A nominal scale differentiates between items or subjects based only on their names or (meta-)categories and other qualitative classifications they belong to; thus dichotomous data involves the construction of classifications as well as the classification of items. Discovery of an exception to a classification can be viewed as progress. Numbers may be used to represent the variables but the numbers do not have numerical value or relationship: For example, a Globally unique identifier. Examples of these classifications include gender, nationality, ethnicity, language, genre, style, biological species, and form. In a university one could also use hall of affiliation as an example.
Nominal scale
Nominal scale
qudt:OrdinalScale
The ordinal type allows for rank order (1st, 2nd, 3rd, etc.) by which data can be sorted, but still does not allow for relative degree of difference between them. Examples include, on one hand, dichotomous data with dichotomous (or dichotomized) values such as 'sick' vs. 'healthy' when measuring health, 'guilty' vs. 'innocent' when making judgments in courts, 'wrong/false' vs. 'right/true' when measuring truth value, and, on the other hand, non-dichotomous data consisting of a spectrum of values, such as 'completely agree', 'mostly agree', 'mostly disagree', 'completely disagree' when measuring opinion.

qudt:Quantity
<p class="lm-para">A quantity is the measurement of an observable property of a particular object, event, or physical system. A quantity is always associated with the context of measurement (i.e. the thing measured, the measured value, the accuracy of measurement, etc.) whereas the underlying quantity kind is independent of any particular measurement. Thus, length is a quantity kind while the height of a rocket is a specific quantity of length; its magnitude that may be expressed in meters, feet, inches, etc. Examples of physical quantities include physical constants, such as the speed of light in a vacuum, Planck's constant, the electric permittivity of free space, and the fine structure constant. </p>
<p class="lm-para">In other words, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum, energy, and weight, and units are used to describe their measure. Many of which are related to each other by various physical laws, and as a result the units of some of the quantities can be expressed as products (or ratios) of powers of other units (e.g., momentum is mass times velocity and velocity is measured in distance divided by time). These relationships are discussed in dimensional analysis. Those that cannot be so expressed can be regarded as "fundamental" in this sense.</p>
<p class="lm-para">A quantity is distinguished from a "quantity kind" in that the former carries a value and the latter is a type specifier.</p>
Quantity
qudt:QuantityDimensionVector
<p class="lm-para">A <em>Quantity Dimension Vector</em> is a relationship between a quantity system, a quantity kind of that system, and one or more dimension vectors. The dimensions of a quantity are expressed as a product of the basic physical dimensions mass, length, time, electric charge, and absolute temperature as \(dim \, Q = L^{\alpha} \, M^{\beta} \, T^{\gamma} \, I ^{\delta} \, \theta ^{\epsilon} \, N^{\eta} \, J ^{\nu}\), where the rational powers, named dimensional exponents, \(\alpha, \, \beta, \, \gamma, \, \delta, \, \epsilon, \, \eta, \, \nu\), are positive, negative, or zero.</p>
<p class="lm-para">For example, the dimension of the physical quantity \(\it{speed}\) is \(\boxed{length/time}\), \(L/T\) or \(LT^{-1}\), and the dimension of the physical quantity force is \(\boxed{mass \times acceleration}\) or \(\boxed{mass \times (length/time)/time}\), \(ML/T^2\) or \(MLT^{-2}\) respectively.</p>
Quantity Dimension Vector
qudt:QuantityKind
A <b>Quantity Kind</b> is any observable property that can be measured and quantified numerically. Familiar examples include physical properties such as length, mass, time, force, energy, power, electric charge, etc. Less familiar examples include currency, interest rate, price to earning ratio, and information capacity.
Quantity Kind
qudt:RatioScale
The ratio type takes its name from the fact that measurement is the estimation of the ratio between a magnitude of a continuous quantity and a unit magnitude of the same kind (Michell, 1997, 1999). A ratio scale possesses a meaningful (unique and non-arbitrary) zero value. Most measurement in the physical sciences and engineering is done on ratio scales. Examples include mass, length, duration, plane angle, energy and electric charge. In contrast to interval scales, ratios are now meaningful because having a non-arbitrary zero point makes it meaningful to say, for example, that one object has "twice the length" of another (= is "twice as long"). Very informally, many ratio scales can be described as specifying "how much" of something (i.e. an amount or magnitude) or "how many" (a count). The Kelvin temperature scale is a ratio scale because it has a unique, non-arbitrary zero point called absolute zero.
Ratio scale
Ratio scale
qudt:SI-Unit
The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units are derived. These SI base units and their physical quantities are: metre for length kilogram for mass second for time ampere for electric current kelvin for temperature candela for luminous intensity mole for the amount of substance. The SI base quantities form a set of mutually independent dimensions as required by dimensional analysis commonly employed in science and technology.
SI Unit
qudt:SystemOfNaturalUnits
In physics, natural units are physical units of measurement based only on universal physical constants. For example the elementary charge e is a natural unit of electric charge, or the speed of light c is a natural unit of speed. A purely natural system of units is defined in such a way that some set of selected universal physical constants are normalized to unity; that is, their numerical values in terms of these units become exactly 1. Examples are Planck Units and Atomic Units. Atomic units (au or a.u.) form a system of natural units which is especially convenient for atomic physics calculations. There are two different kinds of atomic units, which one might name Hartree atomic units and Rydberg atomic units, which differ in the choice of the unit of mass and charge. Planck units are unique among systems of natural units, because they are not defined in terms of properties of any prototype, physical object, or even elementary particle.
System of natural units
qudt:SystemOfUnits
A system of units is a set of units which are chosen as the reference scales for some set of quantity kinds together with the definitions of each unit. Units may be defined by experimental observation or by proportion to another unit not included in the system. If the unit system is explicitly associated with a quantity kind system, then the unit system must define at least one unit for each quantity kind.
System of Units
qudt:Unit
A unit of measure, or unit, is a particular quantity value that has been chosen as a scale for measuring other quantities the same kind (more generally of equivalent dimension). For example, the meter is a quantity of length that has been rigorously defined and standardized by the BIPM (International Board of Weights and Measures). Any measurement of the length can be expressed as a number multiplied by the unit meter. More formally, the value of a physical quantity Q with respect to a unit (U) is expressed as the scalar multiple of a real number (n) and U, as \(Q = nU\).

<p>A system of units is coherent with respect to a system of quantities and equations if the system of units is chosen in such a way that the equations between numerical values have exactly the same form (including the numerical factors) as the corresponding equations between the quantities. In such a coherent system, no numerical factor other than the number 1 ever occurs in the expressions for the derived units in terms of the base units. For example, the \(newton\) and the \(joule\). These two are, respectively, the force that causes one kilogram to be accelerated at 1 metre per (1) second per (1) second, and the work done by 1 newton acting over 1 metre. Being coherent refers to this consistent use of 1. In the old c.g.s. system , with its base units the centimetre and the gram, the corresponding coherent units were the dyne and the erg, respectively the force that causes 1 gram to be accelerated at 1 centimetre per (1) second per (1) second, and the work done by 1 dyne acting over 1 centimetre. So \(1\,newton = 10^5 dyne\), \(1 joule = 10^7 erg\), making each of the four compatible in a decimal sense within its respective other system, but not coherent therein.</p>
