Cooking volume conversion moves between cups, tablespoons, teaspoons and millilitres - and the cup and tablespoon are not the same size in every country. Every common kitchen volume, converted exactly - US, UK, and metric - not a rounded rule of thumb.
| Question | Answer |
|---|---|
| Tablespoons in a cup | 16 |
| Teaspoons in a tablespoon | 3 |
| Fluid ounces in a cup | 8 |
| Cups in a pint | 2 |
| Cups in a quart | 4 |
| Cups in a gallon | 16 |
| Fluid ounces in a gallon | 128 |
| Teaspoons in a cup | 48 |
All exact, US customary measurements - not rounded. These are the numbers behind essentially every US recipe conversion, verified against this site's own conversion engine rather than a rule of thumb.
The same word means a genuinely different amount depending on where the recipe is from - a US cup is 236.6mL, but a UK/imperial cup is 284.1mL, about 20% more. A US tablespoon (14.79mL) is close to but not identical to a UK or metric tablespoon (15mL), and an Australian tablespoon is a notable outlier at 20mL - a third larger than the US version. For a recipe with more than a couple of tablespoons of something, that difference is enough to change the result. If a recipe doesn't specify, and reads like it's from outside the US, it's worth checking - and this converter handles US, UK, and metric versions separately rather than treating "cup" and "tablespoon" as universal.
This pairs with the ingredient weight to volume converter for turning any of these volumes into grams for a specific ingredient - since a cup of flour and a cup of sugar don't weigh the same.
Sixteen in the US, but the Australian tablespoon is 20 mL rather than 15, so an Australian cup is 12 tablespoons plus a teaspoon. This is a common source of recipe errors.
No. A US cup is 236.6 mL, a metric cup is 250 mL, and a UK legal cup is 284 mL. For baking, the difference matters.
