public class Measurement
extends Object
implements Cloneable, Serializable
This class implements any quantity as the pair <µ, u>. It provides the full set of operators including addition and subtration of equally dimensioned quantities. It also has a method convert(Unit u_prime) to convert a measurement value µ to µ' for another commensurable unit u'.
