The SI unit can be be used to identify a quantity given the unit. For example: static boolean isAngularVelocity(AbstractUnit unit) {
return unit.toSystemUnit().equals(RADIAN.divide(SECOND)); } assert(REVOLUTION.divide(MINUTE).isAngularVelocity()); // Returns true. toSystemUnit in class AbstractUnit<Q extends javax.measure.Quantity<Q>>public Map<? extends javax.measure.Unit<?>,Integer> getBaseUnits()
