1 US cup = 16 tablespoons = 48 teaspoons = 8 fluid ounces = 236.6 ml. One tablespoon holds 3 teaspoons (14.79 ml) and one fluid ounce is 2 tablespoons (29.57 ml). This converter uses US customary units and passes every amount through millilitres, so any volume converts cleanly to any other.

How cooking volume units relate

US recipe volumes nest neatly: 3 teaspoons make a tablespoon, 2 tablespoons make a fluid ounce, and 16 tablespoons make a cup. Larger amounts keep nesting too — 2 cups make a pint, 2 pints make a quart, and 4 quarts make a gallon. Metric recipes use millilitres and litres instead. Because all of these describe the same physical volume, you can convert between any pair by first expressing the amount in millilitres and then dividing by the millilitres in your target unit. That single hub keeps the arithmetic consistent no matter which direction you go.

target = (amount × ml_per_from) ÷ ml_per_target

1 tsp = 4.92892 ml · 1 tbsp = 14.7868 ml · 1 fl oz = 29.5735 ml · 1 cup = 236.588 ml · 1 L = 1000 ml

Worked example: ¾ cup to tablespoons and millilitres

Start from cups, move through millilitres, then land on the unit you need.

  1. 1
    Note the amount and its unit. Here we convert ¾ cup (0.75 cup).
  2. 2
    Convert to millilitres. 0.75 × 236.588 = 177.44 ml, since 1 cup = 236.588 ml.
  3. 3
    Divide by the target unit’s ml. For tablespoons: 177.44 ÷ 14.7868 = 12 tbsp. For teaspoons: 177.44 ÷ 4.92892 = 36 tsp.
  4. 4
    Read the millilitre value directly. The ml figure is already the metric answer: ¾ cup ≈ 177.4 ml.

US, metric, and UK cups are not the same

The word “cup” means different volumes around the world. A US customary cup is about 237 ml (used here), a metric cup is exactly 250 ml, and a UK/Imperial cup is roughly 284 ml. A recipe that calls for a “cup” can therefore differ by up to 20% depending on where it was written, so always match your measuring cup to the recipe’s origin. Also remember that these are volume conversions: they tell you how much space an ingredient fills, not how much it weighs. Dry ingredients like flour and sugar have very different densities, so 1 cup of flour and 1 cup of sugar weigh different amounts — for weight, use a cups-to-grams tool or a kitchen scale instead.

How many teaspoons are in a tablespoon?
A US tablespoon holds exactly 3 teaspoons (14.7868 ml ÷ 4.92892 ml). So 1 tbsp = 3 tsp, ½ tbsp = 1½ tsp, and 2 tbsp = 6 tsp = 1 fluid ounce.
How many tablespoons are in a cup?
A US cup contains 16 tablespoons, which is also 48 teaspoons or 8 fluid ounces. Half a cup is 8 tablespoons and a quarter cup is 4 tablespoons.
What is the difference between a US cup and a metric cup?
A US customary cup is about 236.6 ml, while a metric cup is exactly 250 ml and a UK/Imperial cup is about 284 ml. This tool uses the US cup, so scale up slightly if your recipe is metric or British.
How many millilitres are in a cup?
One US cup is 236.588 ml, which most cooks round to 237 ml or even 240 ml for convenience. A metric cup, by contrast, is exactly 250 ml.
Is a fluid ounce the same as an ounce of weight?
No. A fluid ounce measures volume (29.5735 ml) while an ounce measures weight (about 28.35 g). They only match for water; for flour, sugar, or butter the two differ, so never swap them.
Can I use this converter for dry ingredients?
Yes for volume — a cup, tablespoon, or teaspoon of a dry ingredient still fills the same space. But to get grams you need the ingredient’s density, so use a cups-to-grams converter or a scale for weight.
