Cooking Measurement Converter
Convert cups, tablespoons, teaspoons, fluid ounces, millilitres and litres for recipes — instant, both-way conversion with a reference table.
About the Cooking Measurement Converter
This cooking measurement converter switches between the volume units recipes use around the world: teaspoons, tablespoons, fluid ounces, cups, pints, quarts, gallons, millilitres and litres. Enter a value, pick your from and to units, and the answer appears instantly with a handy table of common amounts.
It uses US customary measures — the ones in American cookbooks and food blogs — where a cup is 236.588 mL, a tablespoon is 14.79 mL and a teaspoon is 4.93 mL. That matters because a metric cup (250 mL) and an imperial tablespoon differ, and using the wrong one throws off baking especially.
Everything computes locally in your browser, so it's a fast kitchen companion for scaling recipes, converting international measurements and swapping between spoons, cups and metric quantities.

Frequently Asked Questions
How many millilitres are in a cup?
A US customary cup is 236.588 mL, usually rounded to 237 mL or even 240 mL for nutrition labels. A metric cup, common in Australia and Europe, is 250 mL. This converter uses the US cup, so check where your recipe comes from if precision matters, especially in baking.
How many tablespoons are in a cup?
16 US tablespoons make one US cup, and there are 3 teaspoons in a tablespoon, so a cup is 48 teaspoons. Half a cup is 8 tablespoons and a quarter cup is 4. These ratios hold in the US customary system this tool uses.
Are US and UK cooking measurements the same?
No. A US cup is about 237 mL while a metric/UK cup is 250 mL, and a US tablespoon is 14.79 mL versus 15 mL metric or 17.76 mL imperial. The differences are small per spoon but add up in larger quantities, so match your recipe's system.
How do I convert dry ingredients like flour?
This tool converts volume, which works directly for liquids. Dry ingredients are trickier because weight per cup varies — a cup of flour is about 120 g but a cup of sugar is about 200 g. For accurate baking, weigh dry ingredients on a scale rather than converting by volume.
How many teaspoons are in a tablespoon?
Exactly 3 teaspoons make 1 tablespoon in both US and metric systems. So 1 tablespoon is 3 tsp, and half a tablespoon is 1.5 tsp. This is one of the few spoon ratios that's consistent across measurement systems.
