UK fuel economy is traditionally expressed in miles per gallon (mpg) using the imperial gallon. A car doing 40 mpg (UK) = 7.06 L/100 km. UK washing machines are rated in litres but bathtubs and hot water tanks may be quoted in gallons in older British homes.
The UK imperial gallon (4.546 L) differs significantly from the US gallon (3.785 L) — a source of confusion when comparing UK and American fuel efficiency. "40 mpg" means different things in the UK and USA. British cookbooks pre-1970 use pints and quarts (UK measures); US cookbooks use cups.
