                    UnitSystem unitSystem,
                    DurationUnit referenceUnit,
                    double scaleFactorToReferenceUnit)

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

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

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

Method Detail

getStandardUnit

public final DurationUnit getStandardUnit()

Specified by:

getStandardUnit in class Unit<DurationUnit>

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<DurationUnit>

Returns:

the SI standard coefficients for this unit, e.g., kgm/s2 or m-2s2A or m^-2.s^2.A or m^-2s^2A (not necessarily normalized)
