Just to mention:
I don't know of any country using the metric system that is familiar
with the term "kph". The unit symbol is "km/h" and so everbody uses *kmh*.
AFAIK is "kph" an expressession from American English. And since the
folks over there aren't experts on the metric system ;-) you should be
careful joining their terminology.

just my 2ct,
Sven

Ps: KiloPerHour also wouldn't make much sense as well. That could be
thousand grams, volts, rabbits, everything.
