Cooking Measurement Converter
Convert cooking volumes between millilitres, teaspoons, tablespoons, fluid ounces, cups, pints and litres. Each unit has a millilitre value, so the converted amount is your amount times the from-unit factor divided by the to-unit factor. One US cup is 236.588 ml, so 1 cup converts to about 236.6 ml.
Volumes use the US cup (236.588 ml) and US pint (473.176 ml). Dry ingredients vary by density, so a cup of flour and a cup of sugar weigh differently even at the same volume.

How the cooking conversion is worked out
Every unit here has a value in millilitres, so the converter multiplies your amount by the from-unit's millilitre value and divides by the to-unit's millilitre value. A teaspoon is 4.92892 ml, a tablespoon is 14.7868 ml, a fluid ounce is 29.5735 ml, a US cup is 236.588 ml, a US pint is 473.176 ml and a litre is 1000 ml.
This uses the US cup of 236.588 ml, not the metric cup of 250 ml, a difference of about 5.6 percent that can matter in baking. So 1 cup converts to about 236.6 ml. The result is shown to three or four significant figures, which is plenty for kitchen use.
How to use the cooking measurement converter

- Pick the unit you want in the To dropdown and read the converted amount.
Worked examples
Cups to millilitres
Inputs: 1 cup converted to ml
Result: About 236.6 ml, using the US cup. A metric-cup recipe would mean 250 ml instead.
Tablespoons to teaspoons
Inputs: 1 tablespoon converted to teaspoons
Result: Exactly 3 teaspoons, since a tablespoon is 14.7868 ml and a teaspoon is 4.92892 ml.
Limitations and common mistakes
Edge cases and limitations
- This converts volume only. Dry ingredients vary by density, so a cup of flour and a cup of sugar weigh differently at the same volume.
- It uses US cups (236.588 ml) and US pints (473.176 ml), which differ from metric and UK imperial measures.
- Tiny rounding occurs because the result is shown to a few significant figures.
Common mistakes
- Assuming a cup is 250 ml, which is the metric cup, not the US cup this tool uses.
- Converting weight to volume directly, when the answer depends on what the ingredient is.
Frequently asked questions
How many millilitres are in a cup?
This converter uses the US cup, which is 236.588 ml. So 1 cup converts to about 236.6 ml, and half a cup is roughly 118.3 ml. A metric cup is a round 250 ml, so recipes using metric cups will differ slightly.
What is the difference between a US cup and a metric cup?
A US cup is 236.588 ml and a metric cup, common in Australia and parts of Europe, is 250 ml. That is a difference of about 5.6 percent, which can matter in baking. This tool uses the US cup throughout.
How many teaspoons are in a tablespoon?
One tablespoon is 14.7868 ml and one teaspoon is 4.92892 ml, so a tablespoon is exactly three teaspoons. If a recipe calls for a tablespoon and you only have a teaspoon, measure three level teaspoons.
