public final class BaseUnit<Q extends javax.measure.Quantity<Q>> extends AbstractUnit<Q>
This class represents the building blocks on top of which all others physical units are created. Base units are always unscaled SI units.
When using the standard model,
all seven SI base units are dimensionally independent.

AbstractUnitSI unit from which this unit is derived.
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 javax.measure.UnitConverter getSystemConverter() throws UnsupportedOperationException
