That's one I would have thought someone would have found a good while ago.  At least it's an easy one to fix: Divide area by units squared, not by units.

Just filed it and it's now Issue #669.

At least it should be an easy one to fix.  For area, multiply or divide by the conversion factor squared instead of just that factor itself.  (Also suggested to print the answer with an indication the units are square units.)

Thanks for the help!
