Prefixes

The following prefixes can be prepended to any unit (without space in between). Whenever some ambiguity arises, for example for the nuclear magneton "muN", which could also mean micro Newton, the first definition (without prefix, i.e. nuclear magneton) is used. From version 1.5, the prefixes and the units can be spelled out completely. Thus the micro Newton can be entered in several different forms: "muNewton", "microN", "MicroNewton", ...
