About Cooking Units
Convert recipe volumes between US cups, spoons, ounces, and metric milliliters and liters.
US kitchen measures are all defined off the milliliter: a cup is 236.588 ml, a tablespoon 14.7868 ml, a teaspoon a third of that. Enter any amount and convert across cups, pints, quarts, gallons, spoons, ounces, and metric.
The grams option assumes water-like density (1 ml ≈ 1 g) — fine for stocks and milk, wrong for flour and honey, which need their own densities. Everything runs in your browser.
Where it is used
