Cups to ml Converter

Why use a volume converter?

Recipes, drink formulas, product labels and technical specifications often use different volume units. This tool puts US teaspoons, tablespoons, cups, pints, quarts and gallons alongside milliliters, liters and cubic units for quick checks.

tsp, tbsp, fl oz, cup, pt, qt and gal use US customary liquid definitions. One US cup is about 236.588 ml, while a metric recipe cup is commonly 250 ml, so check the recipe source.
