Hi dinos,

re:
> So, is it possible to change the unit for the volume calculator independently of the main preferences?

Sorry no there isn't any facility for this built in currently. Right now your choices would be to convert to cm units before the volume calculation, or also just apply the conversion in a calculator. Let's see, 1 cubic mm = 0.001 cubic cm so you'd divide by 1000 in a calculator to get your desired result.

There seems to be various kinds of arithmetic that people want to do on the volume number so I'll see about adding various options there in a future version. Since it only takes such a low amount of effort to use a calculator it's not a priority right now for the v4 release, sorry.
