How to convert milliliters to cups
cups = milliliters ÷ 236.5882365
1 milliliter is one thousandth of a liter (1 cubic centimeter). 1 US cup is exactly 8 US fluid ounces (half a US liquid pint).
Dividing by 236.5882365 is exact. Written as a multiplication the factor is a repeating decimal, 1 mL = 0.00422675283773… cup, so a rounded multiplier such as 0.004227 is slightly off. This converter keeps the exact fraction (2000000/473176473) and rounds only the result it shows.
Worked example: 500 mL
- Start with the value in milliliters: 500 mL.
- Divide by 236.5882365, because 1 cup = 236.5882365 milliliters: 500 ÷ 236.5882365 = 2.113376419….
- Round to the precision you need: 2.11 cups to two decimals.

Which cup, tablespoon and teaspoon?
All kitchen measures on this page are US customary: 1 cup is 8 US fluid ounces (236.5882365 mL), 1 tablespoon is half a fluid ounce (14.78676 mL) and 1 teaspoon is a third of a tablespoon (4.928922 mL). Cups and spoons sold in other countries can hold a different amount, so for a recipe written outside the United States check which measure the author means.
