Frequently Asked Questions
How many milliliters are in a US cup?
One US customary cup is 236.588 mL. In practice, recipes and measuring cups round to 237 mL or even 240 mL — the US 'legal' cup used on nutrition labels is defined as exactly 240 mL.
What is the difference between the US legal cup and the customary cup?
The customary cup (used in recipes) is 236.588 mL — half a US pint. The legal cup (used on FDA nutrition labels) is defined as exactly 240 mL. The 1.4% difference rarely matters in cooking but explains why label servings and measuring cups don't quite agree.
How big is the cup that comes with a rice cooker?
Rice cooker cups are 180 mL — the traditional Japanese gō measure, not a US cup (237 mL). Using a US measuring cup for rice cooker recipes adds about 30% too much rice for the marked water lines.
Should I measure flour in cups or milliliters?
Neither is ideal — flour compacts, so volume measures vary by up to 20% depending on scooping technique. Weight (grams) is the accurate method: one US cup of all-purpose flour weighs about 120–125 g. For liquids, cups and milliliters are equally reliable.
How much is 100 mL when measured in cups?
100 mL = 0.42 US cups — a bit less than half a cup. Useful inversions: ⅓ cup ≈ 79 mL, ⅔ cup ≈ 158 mL, and 1 metric cup (used in Australia) is exactly 250 mL.
