    >>100 milli Farad (aaah!). - 100 mF
100,000 uF,  0.1F,  Or maybe 0F1.  All the caps of this size that
I've actually SEEN have been labeled as one of the first two.

Maybe I'm getting old, but I can remember when caps were pretty exclusively
named on 6ish exponents.  MicroFarads (useful in powersupplies) and
PicoFarads (or MicroMicroFarads) (useful in the RF sections.)  NanoFarads
seemed to show up when the range became relvannt to digital electronics (all
those bypass caps.)  I've not yet EVER seen milliFarads.
