Kitchen Measurement Conversion Calculator
Written by Thierno Sadou Diallo, formula verified per our methodology • Last checked on 9/5/2026
1 teaspoon = 5 ml, 1 tablespoon = 15 ml, 1 cup = 250 ml (metric convention). This converter switches between volume units instantly.
Explanation
This converter works only with volume, never weight: converting a cup of flour or a cup of sugar into grams would give two different results, since the weight of the same volume depends on the ingredient's density (sugar is denser than flour). For a reliable result in grams, use a kitchen scale rather than a generic volume-to-weight conversion. Watch out for the "cup": this calculator uses the metric convention (1 cup = 250 ml), common in French-language recipes, but different from the US cup (about 237 ml) — a tiny difference for most recipes, but worth keeping in mind for precision baking. To adjust a recipe's quantities for a different number of servings, see our recipe portions calculator.
Example: converting 1 cup to spoons
Inputs
Quantity: 1. Unit: cup.
Calculation
1 cup = 250 ml. In tablespoons (15 ml each): 250 ÷ 15 ≈ 16.67. In teaspoons (5 ml each): 250 ÷ 5 = 50.
Result
1 cup equals 250 ml, about 16.67 tablespoons, or 50 teaspoons.
Frequently asked questions
Why doesn't this converter offer a conversion to grams?
Because a volume only converts to weight if you know the ingredient's density: 250 ml of flour doesn't weigh the same as 250 ml of honey. A table of ingredient densities is a topic of its own; for now, use a kitchen scale for a reliable weight measurement.
Is a cup exactly 250 ml everywhere?
No. This calculator uses the metric convention (250 ml), common in French-language recipes. The standard US cup is about 237 ml — a difference generally negligible in everyday cooking, but one that can matter in precision baking.
Are teaspoons and tablespoons standardized?
Yes, in French-language recipes, a teaspoon measures 5 ml and a tablespoon 15 ml — these are the conventional values used here, independent of the actual size of your table cutlery.
