Actually, there are a lot of anomolies around the world. Eastern Europe
and Russia doggedly cling to using windspeed in Meters/second and have
reluctantly accepted using feet for altitude, though there are still a
lot of published platform altitudes of something like "2746 feet"

I learned to fly in France in the 1980s and they used a weird combination of
feet and meters. Altimeters read in feet,and minimum safe altitudes were
charted in feet. But charted obstructions and airspace restrictions were in
meters. Everyone set QFE (altimeter reads zero on the ground) for takeoff,
then reset the altimeter to QNH if leaving the traffic pattern. Flight levels
began at 3500 feet.

Can any Europeans out there tell me if it's still like that?
