Cooking Measurement Converter
The cooking measurement converter lets you quickly convert between US, UK, and metric kitchen units. Whether you're following an American recipe with cups and tablespoons or a European recipe with milliliters, this tool handles the conversion instantly.
Recipe measurements vary widely between countries. US cups differ from UK cups, and tablespoon sizes aren't universal. This converter covers all common cooking volumes — cups, tablespoons, teaspoons, fluid ounces, pints, quarts, and metric units — so your recipes turn out right every time.
How it works
All conversions use milliliters (mL) as the base unit. Key relationships: 1 US cup = 236.59 mL, 1 UK cup = 284.13 mL, 1 US tbsp = 14.79 mL, 1 UK tbsp = 17.76 mL, 1 US tsp = 4.93 mL, 1 US fl oz = 29.57 mL, 1 UK fl oz = 28.41 mL.
Use cases
- Converting American recipes to metric measurements
- Adapting British recipes for US measuring cups and spoons
- Scaling recipe ingredients up or down
- Converting between fluid ounces and milliliters for baking
Frequently asked questions
How many milliliters are in a US cup?
One US cup equals 236.59 mL. A UK (imperial) cup is larger at 284.13 mL, and the metric cup used in Australia and much of Europe is 250 mL, so it is important to know which cup a recipe means before converting.
How many tablespoons are in a cup?
A US cup holds 16 US tablespoons, since 1 US cup is 236.59 mL and 1 US tablespoon is 14.79 mL. In the UK system the ratio differs slightly because a UK tablespoon is 17.76 mL.
Is a US tablespoon the same as a UK tablespoon?
No. A US tablespoon is 14.79 mL while a UK tablespoon is 17.76 mL, so they are not interchangeable. Australian tablespoons are different again at 20 mL, which can noticeably affect recipes that use several spoonfuls.
How many teaspoons are in a tablespoon?
There are 3 teaspoons in 1 tablespoon in both the US and UK systems. In US measures that means 1 tablespoon of 14.79 mL equals three teaspoons of about 4.93 mL each.
How do I convert fluid ounces to milliliters?
Multiply US fluid ounces by 29.57 to get milliliters, or UK fluid ounces by 28.41. Note that US and UK fluid ounces differ, so always check which system your recipe uses before converting.
