Chris, Try the V4ExtendUnits package at my web site. The BaseSI command converts all the units to base SI units and then simplification automatically occurs. Needs["Miscellaneous`V4ExtendUnits`"] Ampere Meter Meter/Joule Tesla % // BaseSI (Ampere*Meter^2*Tesla)/Joule 1 If you supplied a valid email address, assuming 'not valid' is not you address, you could receive a reply much sooner. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: KaeL [mailto:not_valid at w.pl] To: mathgroup at smc.vnet.net Hi folks, I admit I am not too experienced mit M. (v. 5.1). My problems regards simplification of unit equations. Consider such a simple entry: Simplify[Ampere Meter Meter/Joule Tesla] Explanation for non-physicist: this is equal to 1 Usage of "<<Miscellaneous`Units`" does not help here, as this package is rather _conversion_ (SI into cgs, .i.e Tesla into Gauss) oriented. Running "<<Miscellaneous`PhysicalConstants`" does not help either, as this package rather _introduces/defines_ the units. And you would need here sort of relation between units-am I right? Any idea how to solve my problem? Regards, Chris
