CV?

Seems reasonable to me.  Because you're a scientific organization, however, I 
would think that you wouldn't need some of the units (e.g., "arpentlin").

Sorry, but no.

Personally, I'd restrict the input units to be ISO-compliant (meters, 
kilograms, etc.) but allow the user to input a scale factor.  Probably wouldn't 
work, though, as different users would choose slightly different scale factors.

Good luck.
