When you need this
Road signs switch at borders: the UK and US post miles while Europe posts kilometres, so rental-car odometers and fuel-range estimates need converting. Running races flip the other way — 5Ks and 10Ks are metric, marathons are quoted in miles in the US. Road-trip planning lives on this conversion.
