java.lang.Objectorg.osgi.util.measurement.Unit
A unit system for measurements. This class contains definitions of the most common SI units.
This class only support exponents for the base SI units in the range -64 to +63. Any operation which produces an exponent outside of this range will result in a Unit object with undefined exponents.
