Quite correct. The units in any system of measurement used must be converted to hex to be processed by the computer. It makes little difference to the computer if the system of measurement is metric or British Imperial or anything else.

I note that Iron Gate Studio did not bother to designate the unit of weight used in the UI. I suppose that it does not matter to them.
