How to use this tool

Choose ml → cups or cups → ml.
Enter the amount. Fractions of a cup go in as decimals: ¼ = 0.25, ⅓ ≈ 0.33, ½ = 0.5, ¾ = 0.75.
Read the converted amount.

Uses the US customary cup (≈236.6 ml). US nutrition labels use a rounded 240 ml cup; the UK/Australian metric cup is 250 ml; a Japanese cup is 200 ml.
Volume-to-volume only — for flour, sugar or butter by weight, use cups to grams by ingredient.

Technical details: what the fields mean

Amount millilitres: Volume in millilitres (ml), e.g. from a measuring jug.

Methodology

1 US customary cup = 236.588 ml (8 US fluid ounces). Cups = ml ÷ 236.588; ml = cups × 236.588.

Worked example

500 ml of stock

Inputs: Amount: 500 ml

Result: 2.11 US cups — about 2 cups plus 2 tablespoons.

A 250 ml metric cup in US cups

Inputs: Amount: 250 ml

Result: 1.06 US cups — a metric cup holds about 6% more, which adds up over several cups.

Cups → ml: 1½ cups of milk

Inputs: Amount: 1.5 cups

Result: 354.9 ml — measure 355 ml in a jug.

Cups → ml: ¾ cup of water

Inputs: Amount: 0.75 cups

Result: 177.4 ml.

Practical guidance

If a recipe is Australian, British or from another country using a 250 ml metric cup, use 250 ml per cup rather than this US figure.
Read liquid measures at eye level on a flat surface; looking down at a jug overstates the amount.

Common mistakes

Assuming all 'cup' measurements are the same size — US, metric and Japanese cups all differ.
Using ml for dry ingredients: 250 ml of flour and 250 ml of sugar weigh very different amounts.

About 2.11 US cups, using the 236.6 ml US cup (or exactly 2 metric cups of 250 ml).

About 236.6 ml for a US cup. Recipes using metric cups mean 250 ml.

Yes — 8 US fluid ounces. A UK fluid ounce is slightly smaller (about 28.4 ml vs 29.6 ml), so 8 UK fl oz is about 227 ml.

Uses the US customary cup — recipes written for a 250 ml metric cup or a 200 ml Japanese cup need those figures instead.
