Build a user-defined DurationUnit with a conversion factor to another DurationUnit.

Parameters:

name - String; the long name of the unit

abbreviation - String; the abbreviation of the unit

unitSystem - UnitSystem; the unit system, e.g. SI or Imperial

referenceUnit - DurationUnit; the unit to convert to

scaleFactorToReferenceUnit - double; multiply a value in this unit by the factor to convert to the given reference unit

Method Detail

getStandardUnit
