Cups to Milliliters Converter

The Conversion Factor

Which "Cup" Is This?

Cup sizes vary by country. This converter uses the US customary cup (236.588 mL). If a recipe specifies a metric cup (250 mL, common in Australia and much of Europe) or the UK imperial cup (about 284.13 mL), the results here won't match — multiply by 250 or 284.13 instead.

Typical Kitchen Values

1/2 cup ≈ 118.29 mL, 3/4 cup ≈ 177.44 mL, and 1 1/3 cups ≈ 315.45 mL. These fractional cup measures come up often enough in US recipes that it's worth keeping the base figure — 236.588 mL per cup — in mind rather than re-converting from scratch each time.
