3.3.14

described value domain description

description or specification of a rule, reference, or range for a set of all permissible values (3.3.20) for the value domain (3.3.31)

3.3.15

dimensionality

set of equivalent units of measure (3.3.29)

Note 1 to entry: Equivalence between two units of measure is determined by the existence of a quantity preserving one-to-one correspondence between values measured in one unit of measure and values measured in the other unit of measure, independent of context, and where characterizing operations are the same.

Note 2 to entry: The equivalence defined here forms an equivalence relation on the set of all units of measure. Each equivalence class corresponds to a dimensionality. The units of measure “temperature in degrees Fahrenheit” and “temperature in degrees Celsius” have the same dimensionality, because:a) given a value measured in degrees Fahrenheit there is a value measured in degrees Celsius with the same quantity, and vice-versa, by the well-known correspondences °C = (5/9)*(°F - 32) and °F = (9/5)*(°C) + 32.b) the same operations can be performed on both values.

Note 3 to entry: The units of measure “temperature in degrees Celsius” and “temperature in degrees Kelvin” do not belong to the same dimensionality. Even though it is easy to convert quantities from one unit of measure to the other (°C = °K − 273.15 and °K = °C + 273.15), the characterizing operations in Kelvin include taking ratios, whereas this is not the case for Celsius. For instance, 20° K is twice as warm as 10° K, but 20° C is not twice as warm as 10° C.

Note 4 to entry: Units of measure are not limited to physical categories. Examples of physical categories are: linear measure, area, volume, mass, velocity, time duration, and temperature. Examples of non-physical categories are: currency, quality indicator, colour intensity

Note 5 to entry: Quantities may be grouped together into categories of quantities which are mutually comparable. Lengths, diameters, distances, heights, wavelengths and so on would constitute such a category. Mutually comparable quantities have the same dimensionality. ISO 80000-1 calls these “quantities of the same kind”.

Note 6 to entry: ISO 80000-1 specifies physical dimensions (e.g., length, mass, velocity). This part of ISO/IEC 11179 also permits non-physical dimensions (e.g., value dimensions such as: currency, quality indicator). The present concept of dimensionality equates to what ISO 80000-1 calls Dimensional Product, rather than to Dimension.
