In-depth explanation
Convert litres, millilitres, US and UK gallons/pints, cups, and cooking spoons. US and UK gallons are labelled separately because they differ. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
A US gallon is about 3.785 litres. A UK (imperial) gallon is about 4.546 litres — roughly 20% larger. This tool uses US cup, teaspoon, and tablespoon sizes for cooking measures.
A UK pint is 568.261 ml (exactly 1/8 of an imperial gallon). Tweak the inputs above to compare options, then copy or note the result you need.
US and imperial gallons differ by about 20%. A UK pint in a pub is not a US pint. This tool labels them separately and uses US spoon and cup sizes for cooking measures.
Engineers may want SI litres and cubic metres only — still convert through litres if that is how the drum is labelled. Do not dose medicine from a cooking converter.
