Constructor Detail

ForceUnit

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

Build a user-defined ForceUnit based on its constituent base units, e.g. a N = km.m/s^2.

Parameters:

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

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

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

name - the long name of the unit

abbreviation - the abbreviation of the unit

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

ForceUnit

public ForceUnit(MassUnit massUnit,
                 AccelerationUnit accelerationUnit,
                 String name,
                 String abbreviation,
                 UnitSystem unitSystem)

Build a user-defined ForceUnit based on a MassUnit and an AccelerationUnit, i.e. based on F=m.a.

Parameters:

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

accelerationUnit - the unit of acceleration for the force unit, e.g., m/s^2

name - the long name of the unit

abbreviation - the abbreviation of the unit

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

ForceUnit

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

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

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
