pro tips
Quick mental math: multiply by 240. 1.5 cups becomes 360 ml, close enough for most pans.
1/2 cup is 118 ml and 1/3 is 79 ml — the two numbers half of all recipe cards quietly assume.
4 cups is 946 ml: the reason "a liter of stock" and "4 cups" fight over the last 54 ml.
what it does
The cups-to-milliliters trick multiplies by 236.59 — by 240 when you're estimating and 3 ml won't ruin anything. It fires the moment an American recipe lands in a kitchen where every jug, bottle and carton speaks milliliters.
It shows up in every imported recipe card: 1/2 cup of oil (118 ml, and the bottle has opinions), a cake asking for 2 cups of milk while the blender only owns ml marks, and marinades measured in cups for an oven dish that was manufactured in a metric country.
The rough version: a cup is "about a quarter of a liter". Four cups is 946 ml — just shy of a full liter, which is why 4-cup recipes always leave you one splash short and the soup forgives them.
Type any cup number — halves and quarters welcome — and the widget answers in milliliters instantly, with the math in the hint. Click the result to copy it, and use swap when the jug takes over: the milliliters-to-cups version runs the other direction.
