Well... you'll get it in joules/m^2 -- but you can convert it to
anything you want.  If you have a preferred display quantity for that
kind of quantity (e.g. "joules/cm2") then the system should be able to
automatically convert to it.

There's no way, at present, to ask a Unit for its dimensionality.  Such
a capability could be easily added, however.
