Here in the US, we are slowly inching towards metric....
yes, but at a very metered pace...
Brad

here we have:
flying speed in knots
driving speed kilometers/hours
vertical speed feet/minutes
flying distance in nautical miles
driving distance in kilometers
fuel capacity in liters
fuel consumption gallon per hours

please do not inch towards anything different, even at metered pace!!!
I just got used to the systems and finally they work just fine!!!
