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

durationUnit - DurationUnit; the unit of time for the acceleration unit, e.g., second

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

AccelerationUnit

public AccelerationUnit(SpeedUnit speedUnit,
                        DurationUnit durationUnit,
