conversionFactorToStandardUnit
- the conversion factor by which this number has to be multiplied to convert it to
the standard (e.g., SI) unit.offsetToStandardUnit
- the offset that has to be taken into account for conversions; when converting to a standard
unit, the offset is applied first.public final double toStandardUnit(double value)
