AOL :-) Getting agreement on this could be tricky. The package I'm looking just now has: 12 powers of 10 7 basic SI units 2 'supplementary units 58 'derived' units 23 'other' units 282 "/", "*" & "**" functions and a couple of dozen elementary math functions! I understand how these things can add up. Unfortunately, I'm not sure of the copyright status of this package (I think it is based on the "whitaker" package, but I have made it generic and played around with adding some generic formal packages. There is also a sibling package containing conversions from a couple of dozen non-SI units.
