Private constructorThis class should not be instantiated by users of LuciadRIA.
The factor to convert a quantity expressed in this UnitOfMeasure to a quantity expressed in the standard UnitOfMeasure. This factor is used in combination with the conversionOffset. For a standard Unit Of Measure this multiplier is 1. For a non standard UnitOfMeasure, this is the value which must be used to convert a value in this UnitOfMeasure to the standard UnitOfMeasure. For example, for the "Foot" UnitOfMeasure, the conversionMultiplier is 0.3048 to convert feet to meters.
The conversion offset for this Unit Of Measure. For a standard Unit Of Measure the offset is 0.
For a non standard Unit Of Measure, this is the value which must be used to convert a value in this UnitOfMeasure to the standard UnitOfMeasure. For example, for the "DegreesCelcius" UnitOfMeasure, the conversion offset is 273.15 to convert degrees Celcius to degrees Kelvin (0 degrees celcius corresponds with 273.15 degrees Kelvin).
A more complex example is degrees Fahrenheit: the conversionOffset to calculate convert degrees Fahrenheit to Kelvin is 273.15 - (32 * 5 / 9). The conversionMultiplier is 5 / 9.
The name of this UnitOfMeasure. The name is used to identify the UnitOfMeasure in the UnitOfMeasureRegistry
The QuantityKind this UnitOfMeasure is a measure for. Although this is not strictly necessary, a Unit Of Measure typically refers to a base QuantityKind. An example: the "Meter" UnitOfMeasure is a measure for the "Length" QuantityKind.
In case of a non-standard UnitOfMeasure, this property refers to its standard Unit Of Measure. For example the "Foot" UnitOfMeasure would refer to the "Meter" UnitOfMeasure. If the UnitOfMeasure is a standard UnitOfMeasure, this property refers to itself.
The symbol of a UnitOfMeasure is typically a shorthand notation of it's name. Example symbols are "m" for Meter", "ft" for Foot and "°C" for degrees Celcius.
Converts a measure expressed in the standard UnitOfMeasure to this standard UnitOfMeasure (see standardUnitOfMeasure).
The value to be converted.
The converted value.
Converts a measure expressed in this UnitOfMeasure to the standard UnitOfMeasure (see standardUnitOfMeasure). *
The value to be converted.
The converted value.
Converts a measure expressed in this UnitOfMeasure to the corresponding measure in another, compatible UnitOfMeasure. Compatible UnitOfMeasures share the same base QuantityKind.
The value to be converted
the target UnitOfMeasure. This UnitOfMeasure must be a measure for a compatible QuantityKind (i.e. they must share a common base QuantityKind).
The converted measure
QuantityKind is not compatible with the QuantityKind of this UnitOfMeasure.
A Unit Of Measure is a particular scale for measuring quantities of the same kind (see QuantityKind).
You can discern two types of Units Of Measure: Standard and non-standard Units of Measure.
- Standard Units define a standard measure for a QuantityKind (See QuantityKind).
- A non-standard Unit is always defined in terms of a standard Unit, but applies a conversion
factor and offset.
For example, "Meter" is a base Unit Of Measure that measures quantities of kind "Length" (and also of "Distance", "Height", ... which are subtypes of "Length"). An example non-standard Unit related to the "Meter" Unit Of Measure is the "Foot", which is 0.3048 "Meter".A Unit of measure cannot by created, it can only be retrieved from the UnitOfMeasureRegistry
