Constructor Details

Unit

public Unit(String id,
 String name,
 double scaleFactorToBaseUnit,
 UnitSystem unitSystem)

Create a new ElectricCurrent unit.

Parameters:

id - the id or main abbreviation of the unit

name - the full name of the unit

scaleFactorToBaseUnit - the scale factor of the unit to convert it TO the base (SI) unit

unitSystem - the unit system such as SI or IMPERIAL

Unit

public Unit(String textualAbbreviation,
 String displayAbbreviation,
 String name,
 Scale scale,
 UnitSystem unitSystem)

Return a derived unit for this unit, with textual abbreviation(s) and a display abbreviation.

Parameters:

textualAbbreviation - the textual abbreviation of the unit, which doubles as the id

displayAbbreviation - the display abbreviation of the unit

name - the full name of the unit

scale - the scale to use to convert between this unit and the standard (e.g., SI, BASE) unit

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