Cooking Measurement Converter
Enter a volume and its unit to see the equivalent in teaspoons, tablespoons, fluid ounces, cups, milliliters, and liters.
Uses US customary cooking measurements (1 cup = 236.59 mL). UK and Australian cup/spoon sizes differ slightly — check your recipe's origin if precision matters.
How cooking measurement conversion works
US cooking measurements scale by fixed ratios: 3 teaspoons make 1 tablespoon, 2 tablespoons make 1 fluid ounce, and 16 tablespoons (8 fluid ounces) make 1 cup — all ultimately defined relative to the milliliter.
1 US cup is defined as exactly 236.5882365 mL, which is why these conversions use that precise figure rather than a rounded 240 mL or 250 mL, both of which are used by other measurement systems (UK and metric recipes, respectively).
