Hello, I don't think there is a straightforward way to do this using the standard Miscellaneous`Units` package. I had the same problem many years ago and wrote an enhanced packag with a function ToFundamentalSI which will do exactly what you want. There are other improvements too. You can download it from http://jowett.home.cern.ch/jowett/Accelerator/ConstantsUnits.html The package-defining notebook also contains the documentation.
