Constructor Detail

MassUnit

public MassUnit(String name,
                String abbreviation,
                UnitSystem unitSystem,
                MassUnit referenceUnit,

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

Parameters:

name - the long name of the unit

abbreviation - the abbreviation of the unit

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

referenceUnit - the unit to convert to

conversionFactorToReferenceUnit - multiply a value in this unit by the factor to convert to the given reference unit

Method Detail

getStandardUnit

public final MassUnit getStandardUnit()

Specified by:

getStandardUnit in class Unit<MassUnit>

Returns:

the SI standard unit for this unit, or the de facto standard unit if SI is not available

getSICoefficientsString

public final String getSICoefficientsString()

Specified by:

getSICoefficientsString in class Unit<MassUnit>

Returns:
