It Depends.  Arguably, getting a C is not not "severe punishment."
(need more details.  "C" on a single question?  C on an exam where
ALL the answers had the wrong units?  C as a class grade for a student
who never used the right units?  Or are you talking 25% off full credit
for each answer with the wrong units, later subject to per-class curves
and so on?  25% off for wrong units sounds about right, especially if
there is no work shown (relevant to the units.  "It's not a careless
mistake: you guessed what the units would be, and you guessed wrong.")
And 25% off WOULD normally move you into C territory, right?)
