UnitOfMeasure A standard of measurement for some dimension. For example, the Meter is a UnitOfMeasure for the dimension of length, as is the Inch. There is no intrisic property of a UnitOfMeasure that makes it primitive or fundamental; rather, a system-of-units (e.g. SystemeInternationalUnit) defines a set of orthogonal dimensions and assigns units for eachPhysicalQuantitySubtractionFnMeasureFn
