Kitchen units, reconciled
Recipes mix teaspoons, tablespoons, cups, fluid ounces and millilitres freely, and this converter moves between them so you do not have to guess. The core relationships in the US system are fixed: three teaspoons make one tablespoon, sixteen tablespoons make one cup, and one cup holds eight fluid ounces. In metric terms a US cup is about 237 millilitres, a tablespoon about 14.8 millilitres, and a teaspoon roughly 4.9 millilitres.

Watch which cup you mean
The word cup is not the same everywhere. A US legal cup used on nutrition labels is 240 millilitres, the customary US cup is about 237, a metric cup is exactly 250, and an old imperial cup is around 284. For most cooking the difference is small, but in baking, where ratios matter, it can affect the result, so match the recipe's country of origin. Remember too that these are volume measures; converting flour or sugar to grams depends on the ingredient's density, which a volume converter cannot know.
Where it's used
- Following a US recipe when you only have metric measuring tools, or vice versa
- Scaling a recipe up for a crowd or down for one
- Substituting when you're missing the exact measuring cup
- Converting a cocktail recipe's fluid ounces to millilitres
- Adapting a European recipe written in volume rather than grams
Real-world examples
- 1 US cup equals 16 tablespoons, or 48 teaspoons, or about 237 ml.
- A recipe needs 3 tablespoons of oil but you only have a teaspoon — that's 9 teaspoons.
- 500 ml of stock converts to about 2.1 US cups.
- 6 fluid ounces of milk is 3/4 of a cup.
