Millilitres to US cups divides by 236.588. A 500 mL quantity is 2.11 US cups; 250 mL is 1.06 US cups. Because cups vary by standard (US customary 236.6 mL, US legal 240 mL, metric 250 mL), converting a precise millilitre value to cups always loses a little accuracy — which is why bakers prefer to weigh ingredients in grams rather than measure cups. Use this conversion to approximate, then trust a scale for anything that must rise.
Bakers converting a European or Asian recipe card into US measuring-cup increments rely on this figure constantly. 60 mL of milk is 0.254 cup; 120 mL of yoghurt is 0.507 cup, close enough to round to a half cup; 240 mL of flour-adjacent liquid is 1.014 cups. Because dry ingredients pack differently than liquids, this conversion is only trustworthy for liquids and pourable batters — flour and sugar need a kitchen scale, not a volume conversion, for real accuracy.

A standard medicine dropper is 1 mL. A teaspoon holds 5 mL. A typical wine glass pour is 150 mL.
The milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter, or one cubic centimeter. It is the everyday unit for medication dosing, beverage sizes outside the US, and cooking in most of the world. Note that a US fluid ounce is 29.5735 mL, while a UK fluid ounce is 28.4131 mL.
The US legal cup, as used in nutrition labels, equals exactly 240 mL; the US customary cup, used in recipes, equals 236.5882365 mL (half a US liquid pint, or 8 US fluid ounces). Convertitive uses the customary value, which matches how most US cookbooks specify quantities. UK and Australian metric cups are 250 mL — yet another small but consequential difference.
