That’s not entirely true. The UK and Australia use Imperial measurements quite frequently, especially for speed.
Road distance is miles, running its metres. Except for the marathon. Beer is pints, my milk is litres but you can get pints. The lamb in the fridge for the weekend is 2.3kg, I’m 5’11 and way a little over 14 stone as I’m far, probably because of the 200g of Brie I am thinking about eating tonight. I was looking at a floor plan the other day, the room was 6.5m x 3.8m
We also haven't made the switch to metric time yet ;)
