How would you do it? Using some special set of units has problems with extensibility. Suppose someone tried to add currency and used US dollars as the base and at the same time someone else used euros as the base.
Speaking of currency however, that is another completely different problem as conversions between units of currency are dynamic rather than fixed like all units of physical measurement. Conversions for such units can only be done at runtime. Eric.
