Convert a volume between litres, millilitres, cups, pints, and gallons — for scaling a recipe, filling a tank, or comparing a UK measurement with a US one.
Metric units (litres and millilitres) are identical everywhere, but the named imperial and US units are not, and that trips people up constantly. The section below spells out where they differ.
US and imperial units of the same name are not equal
- Gallon: a US gallon is about 3.785 L; an imperial (UK) gallon is about 4.546 L — roughly 20% bigger. This is why '40 miles per gallon' means different things in the two countries.
- Pint: a US pint is 16 US fl oz (≈ 473 mL); an imperial pint is 20 imperial fl oz (≈ 568 mL), so a UK pint is noticeably larger.
- Cup: a US customary cup is ≈ 237 mL, a US 'legal' cup on nutrition labels is 240 mL, and a metric cup is 250 mL — so for baking, weighing in grams is more reliable.
- Litre and millilitre: defined identically worldwide (1 L = 1,000 mL), which makes converting through litres the safe way to cross between US and imperial.
Frequently asked questions
- Is a US gallon the same as a UK gallon?
- No. A US gallon is about 3.785 litres and an imperial gallon about 4.546 litres — roughly 20% larger. Always check which gallon a figure refers to, especially for fuel economy.
- Which cup should I pick for a recipe?
- Match the recipe's origin: US recipes usually mean a US cup, UK and Australian ones a 250 mL metric cup. Because cups vary, weighing ingredients in grams removes the ambiguity entirely.
- Does this run privately?
- Yes — browser-side arithmetic, no upload, no signup, and it works offline once loaded.
