Since nmol mol-1 is equal to 1e-9, there is no problem with using it as units
in a CF file. It is udunits-compliant. It could even be stated as the
canonical unit in the standard name table.
the point im trying to make is that it would be better to understand
that "mol mol-1" (canonical udunit = 1) is not the same as "m3 m-3"
(canonical udunit = 1).
if you prefer to keep the word "unit" to mean "dimensional unit", then
we could use another term, say "physical quantity" or something.
BTW, we might want to clarify what "udunits-compliant" means. the java
udunit package appears to accept the string "garbage garbage-1". Im not
sure about the udunit C library.
