Type in any box and every other unit updates instantly. All cup, spoon and ounce units use the US customary system.
Recipes never seem to agree on units. One calls for two cups, another for 500 ml, a third for a tablespoon and a half. This cooking measurement converter turns any common kitchen volume into every other one at once. Type a number into cups, tablespoons, teaspoons, fluid ounces, pints, quarts, millilitres or litres, and every other box updates instantly. All the cup, spoon and ounce units here use the US customary system.
What is the Cooking Measurement Converter?
Cooking volumes are a tidy nested system once you know the building blocks. In the US customary measures used here, one tablespoon equals exactly three teaspoons, one fluid ounce equals two tablespoons, one cup equals eight fluid ounces (sixteen tablespoons or forty-eight teaspoons), one pint equals two cups, and one quart equals two pints (four cups). Because every step is a clean multiple, scaling a recipe up or down rarely needs a calculator once the ratios are second nature.
The one place people slip is mixing measurement systems. A US cup is about 236.6 ml, but a metric cup is 250 ml and an old imperial (UK) cup is roughly 284 ml. A US fluid ounce is about 29.57 ml while an imperial fluid ounce is about 28.41 ml. The differences look small per spoon but add up across a full recipe, which is why this tool fixes a single, clearly labelled convention (US customary) and converts everything through millilitres as the common reference.
Volume and weight are also not interchangeable. A cup is a measure of space, not mass, so a cup of flour and a cup of honey weigh very different amounts. This converter handles volume only: it tells you how many millilitres or tablespoons a cup is, not how many grams of a given ingredient fit in it. For dry baking where accuracy matters most, weighing ingredients on a scale is still the most reliable approach.
When to use it
- Following a US recipe with a metric measuring jug, or a metric recipe with US cups and spoons.
- Scaling a recipe up or down and needing the new amounts in a unit your tools actually have.
- Converting a tablespoon or teaspoon amount into millilitres for a measuring syringe or small scale.
- Checking how many tablespoons are in a cup so you can measure without digging out the cup.
- Translating a drink or cocktail recipe written in fluid ounces into ml.
How to use the Cooking Measurement Converter
- Find the unit your recipe uses among the boxes (for example cups or millilitres).
- Type the amount into that box.
- Read the equivalent value in every other unit, which updates instantly.
- Clear the box or type a new number to convert a different amount.
Formula & method
Worked examples
A recipe asks for 1 cup of milk but you only have a millilitre jug and tablespoons.
- Convert to ml: 1 cup × 236.588 ml/cup = 236.588 ml
- Convert to tablespoons: 236.588 ÷ 14.7868 = 16 tbsp
- Convert to teaspoons: 236.588 ÷ 4.92892 = 48 tsp
- Convert to fluid ounces: 236.588 ÷ 29.5735 = 8 fl oz
Result: 1 US cup = 236.588 ml = 16 tablespoons = 48 teaspoons = 8 fluid ounces.
A metric recipe lists 250 ml of stock and you want it in US cups and tablespoons.
- Convert to cups: 250 ÷ 236.588 = 1.057 cups
- Convert to tablespoons: 250 ÷ 14.7868 = 16.907 tbsp
- Convert to fluid ounces: 250 ÷ 29.5735 = 8.454 fl oz
Result: 250 ml ≈ 1.057 US cups ≈ 16.9 tablespoons ≈ 8.45 fluid ounces.
Common US kitchen volume equivalents
| Unit | Teaspoons | Tablespoons | Fluid ounces | Millilitres |
|---|---|---|---|---|
| 1 teaspoon | 1 | 0.333 | 0.167 | 4.929 |
| 1 tablespoon | 3 | 1 | 0.5 | 14.787 |
| 1 fluid ounce | 6 | 2 | 1 | 29.574 |
| 1 cup | 48 | 16 | 8 | 236.588 |
| 1 pint | 96 | 32 | 16 | 473.176 |
| 1 quart | 192 | 64 | 32 | 946.353 |
Why the cup you use matters (volume of one cup)
| Cup type | Millilitres | Fluid ounces (US) |
|---|---|---|
| US customary cup | 236.588 | 8 |
| Metric cup | 250 | 8.45 |
| Imperial (UK) cup | 284.131 | 9.61 |
Common mistakes to avoid
- Treating a US cup and a metric cup as the same. A US cup is about 236.6 ml but a metric cup is 250 ml, a difference of over 5 percent. Across several cups in a recipe this adds up. This tool uses the US cup, so label your source recipe before converting.
- Confusing fluid ounces with weight ounces. A fluid ounce measures volume, while an ounce on a scale measures weight. They only match for water. For flour, sugar or butter, a fluid ounce and a weight ounce are not the same amount.
- Mixing US and imperial fluid ounces. A US fluid ounce is about 29.57 ml but an imperial (UK) fluid ounce is about 28.41 ml. Old British recipes often use the imperial value, so check the origin of the recipe.
- Assuming a cup of any ingredient weighs the same. Volume is not mass. A cup of flour weighs far less than a cup of honey. This converter changes volume units only and cannot tell you the grams of a specific ingredient.

Frequently asked questions
How many ml are in a cup?
One US customary cup is 236.588 ml. Note that a metric cup is 250 ml and an imperial (UK) cup is about 284 ml, so the answer depends on which cup your recipe means. This converter uses the US cup.
How many tablespoons are in a cup?
There are 16 tablespoons in a US cup. A cup is also 48 teaspoons and 8 fluid ounces, since one tablespoon equals three teaspoons and one fluid ounce equals two tablespoons.
How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon. So a tablespoon and a half is 4.5 teaspoons, and half a tablespoon is 1.5 teaspoons.
Are these US or UK measurements?
All the cup, tablespoon, teaspoon, fluid ounce, pint and quart values here use the US customary system. If your recipe is British or Australian, the cup and spoon sizes differ slightly, so the millilitre and litre results will be the most reliable in that case.
Can I convert cups to grams with this tool?
No. Cups measure volume and grams measure weight, and the link between them changes with the ingredient. A cup of flour weighs much less than a cup of sugar or honey. This converter handles volume units only.
How many fluid ounces are in a quart?
A US quart is 32 fluid ounces. It is also 2 pints, 4 cups, 64 tablespoons or about 946.35 ml.
