Learn more about privacyA recipe calling for a gallon means two different amounts depending on which side of the Atlantic wrote it — and the gap is 20%, which is more than enough to ruin the recipe or the fuel-economy figure.
What Volume Converter does
Converts between metric and US customary volumes, and includes the UK gallon separately at 4.54609 L against the US gallon’s 3.785411784 L.
Every cooking unit here is US — cups, pints, quarts and fluid ounces all differ between the US and UK, and quietly mixing the two is how a recipe fails.

- Read the result.
Worth knowing
A UK pint is 568 ml and a US pint is 473 ml — a difference of nearly 20%. In a recipe that is the gap between working and not; in a fuel-economy figure it makes a car look dramatically more or less efficient than it is. If a source does not say which system it uses, the spelling usually tells you: "litre" and "colour" mean UK.
Frequently Asked Questions
Why are US and UK gallons different?
They descend from different historical standards and were never reconciled. The US kept an older wine gallon; the UK redefined its gallon in 1824 as the volume of ten pounds of water. The 20% gap has persisted ever since.
Is a cup here US or UK?
US, at about 237 ml. A metric cup is 250 ml and the UK does not really use cups at all, preferring weight. For baking especially, weigh ingredients if you can — it removes the ambiguity entirely.
How much is a UK pint?
About 568 ml, against 473 ml for a US pint. It is why a pint of beer is noticeably larger in Britain, and why converting drinks measures across the Atlantic needs care.
Which units here are metric?
Litres, millilitres and cubic metres. Everything else is US customary apart from the UK gallon, which is listed separately precisely because the ambiguity causes errors.
