AmountOfSubstanceMeasure | A ConstantQuantity is a PhysicalQuantity which has a constant value, e.g. 3 meters and 5 hours. The magnitude (see MagnitudeFn) of every ConstantQuantity is a RealNumber. ConstantQuantities are distinguished from FunctionQuantities, which map ConstantQuantities to other ConstantQuantities. All ConstantQuantites are expressed with the BinaryFunction MeasureFn, which takes a Number and a UnitOfMeasure as arguments. For example, 3 Meters can be expressed as (MeasureFn 3 Meter). ConstantQuantities form a partial order (see PartialOrderingRelation) with the lessThan relation, since lessThan is a RelationExtendedToQuantities and lessThan is defined over the RealNumbers. The lessThan relation is not a total order (see TotalOrderingRelation) over the class ConstantQuantity since elements of some subclasses of ConstantQuantity (such as length quantities) are incomparable to elements of other subclasses of ConstantQuantity (such as mass quantities) | ConstantQuantity | measure | MagnitudeFn | (=> | |

Mole | SystemeInternationalUnit | SI AmountOfSubstanceUnit. symbol: mol. It is one of the base units in SI. It is defined as follows: the Mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 Kilograms of carbon 12. Note that, when this UnitOfMeasure is used, the elementary entities must be specified - they may be atoms, molecules, ions, electrons, etc. or groups of such particles | MeasureFn | MagnitudeFn | (=> |
