Milliliters to Cups Calculator

Convert milliliters to US cups for recipes, beverages, nutrition labels, and kitchen scaling. The form has one input, Milliliters, and returns Cups (US) rounded to three decimal places.

How to use this calculator

Enter a nonnegative volume in milliliters. The calculator divides by the US cup factor and shows the equivalent in cups. If your recipe starts with fluid ounces, use the ounces to milliliters calculator. For larger containers, the gallons to liters calculator or volume converter may fit better.

Know which cup you mean

A U.S. customary cup is about 236.588 milliliters. A metric cup is often 250 milliliters. Some recipes may use other local definitions. If precision matters, confirm the cup standard used by the recipe or measuring tool.

Conversion formula

For U.S. cups:

$cups = milliliters \div 236.588$

For metric cups:

$cups = milliliters \div 250$

Worked example

For 500 mL:

$500 \div 236.588 = 2.113$

The calculator displays 2.113 cups.

Quick reference

Remember that cups are volume, not weight. For dry ingredients, density changes the gram equivalent.
