What Is This Tool?
A cup-to-ml converter turns the volume measures used in recipes — cups, tablespoons, teaspoons — into milliliters, which is what a kitchen measuring jug or scale actually shows. This matters because 'a cup' isn't a single fixed volume worldwide: the US cup, the metric cup and other local units all differ slightly.
The most common values are a US cup at 240 ml, a metric cup at 250 ml, a tablespoon at about 15 ml, and a teaspoon at about 5 ml. Picking the wrong one rarely ruins a recipe outright, but it can noticeably change the texture of baked goods, so it's worth using the definition your recipe was written with.
Why Use It?
- Converts cup, tablespoon and teaspoon measures to milliliters and liters, and back.
- Covers the US cup (240 ml), metric cup (250 ml) and other common regional cup sizes.
- Instant, bidirectional results as you type.
- Useful for following recipes from another country, scaling a recipe up or down, or converting a measuring cup you own to a recipe written in ml.
- Free and private — the calculation runs entirely in your browser.
How to Use
- Choose the unit you're converting from — cup, tablespoon or teaspoon.
- Select which definition of 'cup' your recipe uses, if relevant (US, metric, or another regional cup).
- Type the quantity to see the milliliter (or liter) equivalent instantly.
- Use the reverse field to convert milliliters back into cups, tablespoons or teaspoons.

Frequently Asked Questions
What is the Turkish standard water glass in milliliters?
The Turkish 'su bardağı' (water glass), a standard household unit used in Turkish recipes, is about 200 ml. It's smaller than a US cup (240 ml) and a metric cup (250 ml), so a Turkish recipe that calls for '1 su bardağı' of flour or milk means roughly 200 ml, not 240 or 250.
What is the difference between a US cup, a Turkish water glass and a metric cup?
They are three different fixed volumes that all get called 'a cup' informally: the US cup is 240 ml, the Turkish water glass is about 200 ml, and the metric cup (used in Australia, the UK and elsewhere) is 250 ml. Using the wrong one in a recipe can shift the total liquid or flour by 10–20%, which is enough to affect baking results. Always match the cup size to where the recipe comes from.
How many milliliters are in a tablespoon and a teaspoon?
A tablespoon is about 15 ml (14.79 ml in the US, 15 ml in the UK and Australia — close enough for cooking), and a teaspoon is about 5 ml (4.93 ml in the US, rounded to 5 ml almost everywhere). Three teaspoons make one tablespoon.
How do I convert milliliters back into cups?
Divide the milliliters by the size of the cup you're using: for a US cup, divide by 240; for a metric cup, divide by 250; for a Turkish water glass, divide by 200. For example, 480 ml is 2 US cups, or 2.4 Turkish water glasses.
