Is it just the UK and US that are left and still stuck with a measuring system from the ancient world?
Full immersion for a few months and it's done. The US has been slooooooooooooly moving in the metric direction for what - 30 years? It's politics, no one want to be the "bad guy" that made us go all the way. Why not get with the rest of the world and go metric (except for knots on the water)?
