Cooking Measurement Converter

About the Cooking Measurement Converter

This converts recipe volume measurements between cups, tablespoons, teaspoons, fluid ounces, millilitres and litres — the everyday rescue when a recipe is written in units your measuring set doesn't have. Convert an American recipe's cups into millilitres, scale tablespoons to teaspoons, or switch between US and metric cups. Choose the units and enter a quantity for an instant result.

How it works

Each measure is defined in millilitres (a volume), so your value converts to millilitres and then to the target unit. The common kitchen equivalents are:

• 1 US cup ≈ 236.6 ml; 1 metric cup = 250 ml (used in Australia, NZ and much of Europe).
• 1 US tablespoon ≈ 14.79 ml = 3 teaspoons; 1 US teaspoon ≈ 4.93 ml.
• 1 US fluid ounce ≈ 29.57 ml; 1 US pint = 2 cups.

Because cup sizes differ by country, the tool lists US and metric cups separately.

Assumptions and behaviour

• These are volume measures (how much space an ingredient takes), which is how cups and spoons work in recipes.
• US and metric cups differ (236.6 ml vs 250 ml), and US spoons are used for tablespoon/teaspoon unless stated — pick the one your recipe intends.
• Results show about 7 significant figures.
• The Swap button reverses the two units.

Limitations — cups to grams

• It can't reliably convert cups or millilitres to grams, because that depends on the ingredient's density. A cup of flour (~120 g), a cup of granulated sugar (~200 g) and a cup of water (~237 g) all weigh different amounts despite being the same volume. For weight, weigh the ingredient or use an ingredient-specific chart — a generic volume-to-grams number would be wrong.
• Cup sizes vary by country (US ≈ 236.6 ml, metric 250 ml, older UK cups differ again), so match the recipe's origin.
• Dry vs liquid measuring cups can differ in practice; for baking accuracy, a kitchen scale beats volume measures.
