How the cups to ml converter calculation works

A US customary cup is 236.5882365 milliliters — 8 US fluid ounces:

milliliters = US cups × 236.588

"A cup" means at least four different things, and this is the single biggest source of failed recipes:

An Australian cup is 5.7% larger than an American one. Across a cake recipe using four cups of flour, that is nearly a full extra US cup of flour, which is the difference between a sponge and a brick.

This converter uses the US customary cup, which is what an American recipe means unless it says otherwise.

Standard fractions:

  • ¼ cup → 59.15 ml
  • ⅓ cup → 78.86 ml
  • ½ cup → 118.29 ml
  • ¾ cup → 177.44 ml
  • 1 cup → 236.59 ml
  • 2 cups (a US pint) → 473.18 ml

Cups measure volume, not weight — and for dry goods that is the real problem. A cup of flour is 120–150 g depending on whether it was scooped or spooned and how settled the bag was. That is a 25% swing on the main structural ingredient. For bread and pastry, weigh in grams; cups are fine for liquids, where volume is exactly what you want.

Enter fractions as decimals above: 0.75 rather than "3/4".
