US or UK? How to tell

If a recipe comes from an American website or cookbook, assume US measures. British recipes usually give metric amounts these days, but older ones might use imperial pints (568 ml) and fluid ounces. Fuel economy figures are another trap: miles per gallon in the UK uses the bigger imperial gallon, so UK mpg numbers look better than US ones for the same car.
