How this is calculated

ml = cups × 236.5882365 (US customary cup, exact)

Cooking from a US recipe with a metric jug: 1 cup is 236.59 ml, ½ cup is 118.29 ml, ⅓ cup is 78.86 ml, ¼ cup is 59.15 ml. Many metric cooks simply use 240 ml per cup — a 1.4% difference that is fine for soups and stews, and noticeable in precision baking.

This page uses the US customary cup (236.5882365 ml exactly — half a US pint). Beware neighbors: the US "legal" nutrition-label cup is 240 ml, the Australian metric cup is 250 ml, and the old imperial cup is 284 ml. A recipe’s origin decides its cup.

Frequently asked questions

How many ml in 1 cup?

236.59 ml for the US customary cup this page uses. Australian recipes mean 250 ml, UK vintage recipes 284 ml — check the recipe’s origin before you pour.

Is 250 ml a cup?

In Australia and New Zealand, yes — their metric cup is defined as 250 ml. For American recipes it is about 5.7% too much, which matters in baking ratios.

How do I measure ⅔ cup with a scale or jug?

⅔ cup = 157.73 ml. For dry ingredients a scale beats any volume measure: flour packs so variably that a “cup of flour” spans 120–150 g.

Why do American recipes use volume at all?

Tradition and speed — cup sets predate cheap kitchen scales in US homes. Professional US bakers weigh, which is the quiet admission of which method is more accurate.
