Constructor Detail

PowerUnit

public PowerUnit(MassUnit massUnit,
                 LengthUnit lengthUnit,
                 DurationUnit durationUnit,
                 String name,
                 String abbreviation,
                 UnitSystem unitSystem)

Define a user-defined PowerUnit based on its constituent base units, e.g. a W = km.m^2/s^3.

Parameters:

massUnit - the unit of mass for the power unit, e.g., kilogram

lengthUnit - the unit of length for the power unit, e.g., meter

durationUnit - the unit of time for the power unit, e.g., second

name - the long name of the unit

abbreviation - the abbreviation of the unit otherwise the abbreviation itself

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

PowerUnit

public PowerUnit(LengthUnit lengthUnit,
                 ForceUnit forceUnit,
                 DurationUnit durationUnit,
                 String name,
                 String abbreviation,
                 UnitSystem unitSystem)

Define a user-defined PowerUnit based on a LengthUnit, a ForceUnit, and a TimeUnit, e.g. a W = N.m/s.

Parameters:

lengthUnit - the unit of length for the power unit, e.g., meter

forceUnit - the unit of force for the power unit, e.g., Newton

durationUnit - the unit of time for the power unit, e.g., second

name - the long name of the unit

abbreviation - the abbreviation of the unit otherwise the abbreviation itself

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

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
