UK roads are miles and yards. Speedometer in MPH and fuel consumption in MPG. The dial on the car also as Kilometres and car manuals state kilometres per litre for fuel consumption which is totally alien, so I have to convert to MPG.
Due to the push to metric, I've memorised various conversion figures, such as 25.4mm to the inch, a pint is 568ml. Beer in pubs is in pints.
If you work on the rail, tracks are in miles, chains, furlongs and yards. Horse racing is in miles and furlongs.
As a pilot I also get to use "Knots", so we are all screwed up!
