@wkerzendorf - I think this is intentional behavior, in the sense that 0 is pretty unambiguous - it doesn't matter what unit system it's in (with the exception of celsius/fahrenheit), 0 m is the same as 0 km etc. It doesn't mean we can't decide to change it, but I'm pretty sure this is intentional, not a bug.
