FCSys requires that the Faraday and gas constants are normalized to one. The structure of the Units package allows those constants to be relaxed, but the models in FCSys generally do not.
Some natural systems of units are not compatible with FCSys. Since the Faraday and gas constants are both normalized, it follows that kB = q. This is not the case for the Planck, Rydberg, and Natural systems of units [http://en.wikipedia.org/wiki/Natural_units].
The quasi-SI sets in this package are named by listing (in alphabetical order) the two units that are not normalized for the sake of setting the Faraday and gas constants equal to one. There are eight possible sets of this type (SIAK, SIAm, SIAs, SIKmol, SIKs, SImmol SIms, SImols).
For more information, please see the documentation for the Units package.
