Most over here who cherish the Europa are more "mature" Brits, so we are used to dealing with both metric and imperial. "2.4 metres of 4" x 2" please."
We even remember £2-12s-6d. which was a fair amount of money in those days.
Currency went metric on 15th February 1971 when a Mars bar went from 9d to 4p overnight.
Most sporting events use metric measurements, but our cricket pitch is still 22 yards, and a soccer free kick requires defenders to be 10 yards from the ball but Rugby Union is all metric.
Confused?
We can handle it all, over here.
