Quick answer

One cup equals 236.59 milliliters; divide mL by 236.59 to find cups. A metric cup is 250 mL, so a metric recipe may use slightly larger servings than a US recipe calling for the same cup count.

Formula & method

cups (us) = milliliters × 0.0042267528
  • mL — value in milliliters
  • cup — result in cups (us)
  • 0.0042267528 — exact conversion factor (1 mL = 0.0042267528 cup)

To convert back, divide by 0.0042267528 (1 cup = 236.588239 mL).

Common mistakes

  • Mixing up unit definitions — Uses the US legal/customary cup (236.6 mL).
  • Rounding too early. Multiply by the full factor (0.0042267528) first, then round only the final cups (us) value.
  • Converting the wrong way. This page goes Milliliters → Cups (US); to go back, divide by 0.0042267528.

Frequently asked questions

Why convert mL to cups instead of just using mL?

If you own US measuring cups (which are marked in cups, not mL), converting back to cups is faster and avoids repeating mental math. Many cooks still use cups, especially in the US.

Is a metric cup the same size as a US cup?

No. A metric cup is exactly 250 mL; a US legal cup is 236.59 mL. The difference is about 6%, which can matter in precision baking. Always check your recipe's origin.

How do I know if a recipe uses US or metric cups?

Check the source country or currency. If it says '1 cup,' it's usually US (236.6 mL) if from the US, Canada, or Australia. If it says 'tasse' (French) or 'taza' (Spanish), it's often metric (250 mL).

What's the fastest way to convert a metric recipe to US measuring?

Divide milliliters by 237 (rounding 236.59) to get cups, then multiply by 16 to get tablespoons. Or use a scale: convert mL to grams using the ingredient's density, then weigh on your US kitchen scale.

Can I just round 236.6 mL to 250 mL to match my metric measuring cup?

For soups, stews, and sauces, rounding to 250 mL is fine (only 6% difference). For baking, pastry, and delicate recipes, stay within 240–245 mL for accuracy.

How many milliliters are in half a cup or a quarter cup?

Half cup (0.5 × 236.6) = 118.3 mL. Quarter cup (0.25 × 236.6) = 59.1 mL. Common metric equivalents: 125 mL ≈ 1/2 cup, 60 mL ≈ 1/4 cup.
