Tips and common mistakes
Volume is where UK and US units part company. A UK pint is 568.26 ml but a US pint is 473.18 ml, a UK gallon is 4.54609 litres while a US gallon is 3.785 litres, and a UK fluid ounce (28.41 ml) is slightly smaller than a US one (29.57 ml). Always pick the unit that matches the source of your figure.
Cup sizes also vary. The US cup used here is 236.59 ml, while a metric cup used in UK and Australian recipes is usually 250 ml. When a recipe does not say which, a difference of a few per cent rarely matters for cooking, but it does matter for baking.
For ingredients by weight, such as cups of flour to grams, use the Cooking conversions calculator, since a cup of flour and a cup of sugar do not weigh the same.
