SIUnit
Note: There is a newer version of this specification see VEC 2.1.0
The SIUnit class can define quantities in the terms of the SI-Unit-System by specifying the corresponding SI prefix (optional) and a SI unit name. The usage of SI units must be the preferred way of expressing units, since these units can be easily translated into other SI units.
