How to Convert mL to Cups (Cooking Measurements)

One US cup is about 237 mL. Learn how to convert millilitres to cups, a handy kitchen table, and why cup sizes differ between countries.

To convert millilitres to cups, divide by 236.6 for US cups (or 250 for metric cups). For example, 500 mL ÷ 236.6 ≈ 2.1 US cups. To reverse it, multiply cups by the same number.

The formula

  • US cups = mL ÷ 236.588
  • Metric cups = mL ÷ 250

Kitchen reference (US cups)

  • 60 mL ≈ ¼ cup
  • 120 mL ≈ ½ cup
  • 240 mL ≈ 1 cup
  • 480 mL ≈ 2 cups
  • 1000 mL (1 L) ≈ 4.2 cups

Cup sizes vary

A "cup" is not universal: a US cup is 236.6 mL, a metric cup is 250 mL, and older UK recipes may use different measures. When a recipe matters, convert to millilitres for a precise, unambiguous amount.
