Ok, attached is a diff with these four units in. Then there are a lot
of quasi-energy units, like K, Hz, cm-1, J/mol, ... What's about
these? They are a little tricky as they implicitely assume
converersion factors of h, c, NA, ... and combinations thereof...

Isotopes or averaged masses? Or better both?
How to name them?
