MPH? Seriously!

Knots make some sense, and I can live with that.
Meters per second are used in many Weather forecasts, and at least are 
based on the Metric system!
kph (or km/h) I can also live with, and is in fact the internal value 
system I use in my program (I convert everything to kph internally).

MPH is an totally outdated system, only still used in the USA and 
England, who refuse to switch to the Metric system.
