public class UnitSystem extends ScopeExtendingAttribute
A unit system as defined by a set of base and derived units.
The various measurement units of a unit system are represented by the parameters of an instance of UnitSystem. The units belong to a number of categories, such as length and time in the International System of Units (SI). Each category has a base unit, for example meter in the length category.
Several basic unit systems are provided with Ptolemy II. They are specified using MoML. Customized unit systems can be created following these examples.
