Dear Maarten
A mole is also a udunit, so mol m-3 and m-3 are different units, and
quantities
with those canonical units also have to have different standard_names. The
standard_name indicates whether the quantity refers to number concentration
or
molar concentration.

Jonathan,
I think you meant to say that if a physical quantity has a different
dimensionality (not unit), then we have to give it a different name.
In my opinion, what's needed in this case is a package that understands
co-ordinate transformations -- in order to convert, for example, values in

I support that suggestion.
