Constructor Detail

DensityUnit

public DensityUnit(MassUnit massUnit,
                   LengthUnit lengthUnit,
                   String name,
                   String abbreviation,
                   UnitSystem unitSystem)

Define user defined density unit based on mass and length. You can define units like kg/in^3 here.

Parameters:

massUnit - MassUnit; the unit of mass for the density unit, e.g., kg

lengthUnit - LengthUnit; the unit of length for the density unit, e.g., meter

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

DensityUnit

public DensityUnit(String name,
                   String abbreviation,
                   UnitSystem unitSystem,
                   DensityUnit referenceUnit,
                   double scaleFactorToReferenceUnit)

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

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 - DensityUnit; 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
