Volume Converter
A general purpose volume converter for moulds, mixing cups and finishing products. It includes both US and UK measures because the difference is large enough to ruin a batch: a US cup is 236 millilitres and a UK cup is 284 millilitres.

- US and UK cups differ by about 20 percent, so check which one a recipe means before you scale a batch.
- A US cup is 8 US fluid ounces. A UK cup is 10 UK fluid ounces.
Every figure on this page is worked out from millilitres, and the page states the factor rather than hiding it.
Questions people ask
How many millilitres are in a US cup?
A US cup is about 236.6 millilitres. A UK cup is about 284.1 millilitres. For resin and soap recipes, work in millilitres or grams rather than cups, because small measuring errors compound across a batch.
How many cups are in a litre?
About 4.23 US cups or about 3.52 UK cups in one litre. The difference matters more than people expect when scaling a recipe up.
