About Cooking

Volume in the kitchen

Recipes use cups, tablespoons and teaspoons (US) or milliliters (metric). This converter bridges them so you can follow any recipe.

Handy equivalents

1 US cup is about 236.6 ml, 1 tablespoon about 14.79 ml, 1 teaspoon about 4.93 ml, and 3 teaspoons make 1 tablespoon.

Dry vs liquid

These are volume conversions. For dry ingredients like flour, weight (grams) is more accurate than volume, so use a scale when precision matters.

Frequently asked questions

How many tablespoons in a cup?

About 16 US tablespoons in a US cup.

Is a US cup the same as metric?

No — a US cup is about 236.6 ml, while metric cups are often 250 ml.

Should I weigh dry ingredients?

Yes, weighing in grams is more accurate than volume for flour and sugar.

Understanding Cooking in depth

What this converter solves

Recipes from different countries use different measuring systems, and getting them wrong can ruin a dish. This tool converts between metric volumes (millilitres, litres) and the US/UK kitchen units — cups, tablespoons, teaspoons and fluid ounces — so you can follow any recipe with confidence.

Key kitchen equivalents

The conversions that come up constantly: 1 US cup ≈ 236.6 ml, 1 tablespoon ≈ 14.79 ml, 1 teaspoon ≈ 4.93 ml, and there are 3 teaspoons in a tablespoon and 16 tablespoons in a US cup. A UK/Commonwealth metric cup is 250 ml, slightly larger than a US cup — a difference big enough to matter in baking.

Why weighing beats measuring for dry goods

These are volume conversions, which work well for liquids but are unreliable for dry ingredients. A 'cup' of flour can vary by 20% or more depending on how it is scooped and settled. For accurate baking, professionals weigh dry ingredients in grams. Use this converter for liquids and quick estimates, and a kitchen scale when precision counts.

US versus UK measures

As with volume generally, US and UK fluid ounces and cups differ slightly. This converter includes both so a recipe written in either system comes out right. When a recipe just says 'cup' without specifying, converting to millilitres removes the ambiguity entirely.

Everyday uses

Convert foreign recipes to units you have measuring tools for, scale recipes up or down, and switch between spoons, cups and millilitres. Everything runs in your browser, instantly and offline.
