How to use the us, uk and australia cup and spoon converter
- Enter an amount and choose its unit: teaspoons, tablespoons, fluid ounces, cups or pints.
- Choose the measuring system the amount comes from: US, imperial, metric or Australian.
- Read the volume in milliliters and in every other unit and system.
- Use the table to see one unit in every system at once.
Formula
US: fluid ounce 29.5735295625 mL; cup 8 fl oz; tablespoon 1/2 fl oz; teaspoon 1/6 fl oz; pint 16 fl oz
Imperial: fluid ounce 28.4130625 mL; pint 20 fl oz; cup 10 fl oz; tablespoon 5/8 fl oz; teaspoon 5/24 fl oz
Metric: cup 250 mL, tablespoon 15 mL, teaspoon 5 mL
Australian: cup 250 mL, tablespoon 20 mL, teaspoon 5 mL
Everything is converted to milliliters first and then divided by the size of each target unit.
A cup, a spoon and a pint
1 US cup is 236.588 mL. That is 0.946 of a metric cup, 16 US tablespoons, 11.829 Australian tablespoons and 8.327 imperial fluid ounces. 1 Australian tablespoon is 20 mL, which is 1.353 US tablespoons or 1.333 metric tablespoons.
1 imperial pint is 568.261 mL, which is 2.402 US cups, 19.215 US fluid ounces and 28.413 Australian tablespoons. A US pint is only 473.176 mL, so a recipe that says pint can differ by 20 percent depending on where it was written.
Why the same word means different amounts
The US customary cup, tablespoon and teaspoon are defined from the US fluid ounce. The older imperial units come from a different, slightly smaller ounce and a larger pint. Metric measuring sets, used in most countries now, round everything to 250, 15 and 5 mL, and Australia kept a tablespoon of 20 mL. A recipe that does not say which it uses can come out different by up to a third on a tablespoon.
For US cooking conversions by weight use the ingredient grams to cups converter, for US-only unit changes the cooking measurement converter, for scaling recipes the recipe scaler, and for oven times the air fryer conversion calculator.
Volume is not weight
This page converts volume to volume only. A cup of flour, sugar or butter weighs a different amount in each case, and even the same flour varies with how it is scooped. For accuracy in baking, weigh the ingredients, and use these conversions for liquids and for matching a measuring set to a recipe.
Assumptions and limits
- The imperial cup is half an imperial pint, 284.13 mL, the older UK cup. Modern UK recipes usually use the metric cup of 250 mL.
- The imperial tablespoon is 5/8 of a fluid ounce, 17.758 mL, and the teaspoon is a third of that.
- Metric and Australian measures have no fluid ounce or pint in this tool, and the page says so if you choose one.
- Recipes can use their own sizes, so check the source. This page uses definitions in common use.
Frequently asked questions
How many milliliters is an Australian tablespoon?
An Australian tablespoon is 20 mL, which is a third larger than the 15 mL metric tablespoon used in most other countries and about 35 percent larger than the US tablespoon of 14.79 mL.
Is a UK cup the same as a US cup?
No. A US cup is 236.588 mL. Modern UK recipes use a 250 mL metric cup, and older ones a cup of half an imperial pint, 284.13 mL.
How many ounces are in an imperial pint?
An imperial pint has 20 imperial fluid ounces, 568.261 mL. A US pint has 16 US fluid ounces, 473.176 mL, so the imperial pint is about 20 percent larger.
Can I convert cups of flour to grams here?
No, because flour density varies. Use the ingredient converter for approximate weights, and weigh the ingredient for accurate baking.
