Constructor Detail

AccelerationUnit

public AccelerationUnit(LengthUnit lengthUnit,
                        DurationUnit durationUnit,
                        String name,
                        String abbreviation,
                        UnitSystem unitSystem)

Define user defined acceleration unit based on length and time. You can define units like meter/second^2 here.

Parameters:

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

durationUnit - the unit of time for the acceleration 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

AccelerationUnit

public AccelerationUnit(SpeedUnit speedUnit,
                        DurationUnit durationUnit,
                        String name,
                        String abbreviation,
                        UnitSystem unitSystem)

Define user-defined acceleration unit based on speed and time. You can define units like (mile/hour)/second here.

Parameters:

speedUnit - the unit of speed for the acceleration unit, e.g., knot

durationUnit - the unit of time for the acceleration 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
