I was shocked and offended by the fact that neither units nor qalc (the command line programs) know about the talent unit of weight.

except I was wrong, units *does* know about the talent, but only the Attic and the Aeginetan ones.

It's still missing the Babylonian one, which is the one I was looking for, but nevermind.

(also: 90 kg for an axe? 60 kg for the blade of a dagger? 300 kg carried by one person? I can see how one needs to be two thirds god to use this kind of equipment :D )
