How cooking converter works

Recipes mix measurement systems โ€” a US recipe calls for cups and tablespoons, a European one for milliliters. This converter moves a quantity between all common cooking volume units so you can follow any recipe with the measuring tools you have.

Conversions go through milliliters as a common base using exact US customary values: 1 cup = 236.588 ml, 1 tablespoon = 14.7868 ml (3 teaspoons), 1 teaspoon = 4.92892 ml, 1 fluid ounce = 29.5735 ml, 1 pint = 473.176 ml, 1 quart = 946.353 ml, 1 liter = 1000 ml, and 1 gallon = 3785.41 ml.

Enter a value, choose the unit you have and the unit you want, and the result is shown to six decimal places along with every other unit for reference. Use it to scale recipes, halve ingredients, or translate an international recipe into the units printed on your measuring cups.
