About the Volume Converter
Cooking, chemistry and fuel figures all use volume, and almost none of them agree on a unit. This converter covers the metric side of millilitres, centilitres, litres, cubic centimetres and cubic metres, together with the messier American and imperial side of teaspoons, tablespoons, cups, fluid ounces, pints, quarts, gallons and the oil barrel.
The gallon is the trap. A US gallon is 3.785411784 litres while an imperial gallon is 4.54609 litres, roughly 20 percent larger, so a fuel economy figure quoted in miles per gallon means two different things depending on which side of the Atlantic it came from. US and imperial fluid ounces are listed separately too, because they differ by about four percent.
Recipe conversion is the most frequent use. A US cup is 236.5882365 millilitres, which is why a 250 ml measuring jug never quite lines up with an American recipe. Paste one quantity per line to handle a whole ingredient list at once. For dry ingredients measured by mass instead, switch to the Weight Converter, since flour and sugar do not share a density.
How to use
- Paste the quantities, one per line.
- Choose the source volume unit and the target.
- Check the printed factor if two gallons or ounces are involved.
- Copy the converted quantities.
Common questions
- How many millilitres are in a US cup?
- 236.5882365 millilitres. The metric cup used in Australia is 250 millilitres, which is a different unit.
- Which gallon should I choose?
- Use the US gallon for American figures and the imperial gallon for British or older Commonwealth figures.
- Is a cubic centimetre the same as a millilitre?
- Yes, exactly. That is why engine sizes quoted in cc and in litres line up so neatly.
- Does it know the oil barrel?
- Yes. The barrel option is 158.987294928 litres, the standard 42 US gallon barrel used for crude oil.
