How the cups-to-ml converter works
A US cup is 236.6 ml and a metric cup is 250 ml — a difference of about 6%. Pick the cup your recipe uses: American recipes mean US cups, Australian and most metric recipes mean metric cups. The tool converts both ways and shows fluid ounces too.
Watch out for
The classic mistake is assuming all cups are the same. A recipe that says 2 cups of milk is 473 ml in the US and 500 ml in metric — 27 ml is not much in a soup, but it matters in a custard. When a recipe does not say which cup it means, check where it was published.
