convert

public Quantity convert(Quantity qty,
                        Unit unit)
                 throws java.rmi.RemoteException

Convert the input quanity into a new Quanity with the specified Unit. The category of the unit is first determined and the appropriate Unit Conversion is retrieved. The Quantity is the converted first to the atomic unit and then to the requested unit.

convert

public Quantity convert(Quantity qty,
                        Unit unit,
                        java.lang.String category)
                 throws java.rmi.RemoteException
