Allowing conversion between units having different dimensions and allowing fundamental units whose dimensions are not fundamental e.g. quarts for volume is very very difficult to implement. Off hand, I think that it requires defining some special system (probably SI) and converting through that system.
Ah. Our first communication breakdown. :) By "system", I'm talking about a set of units regardless of their respective dimensions. For example, foot and ounce are two units of the "Imperial" system of units. Meter and gram are two units of the SI system of units. What you are talking about are compatible units. That is, units of the same dimension whose measured values can be converted from one to the other. Just to clear things up a bit... Eric.
