Whether you are following an American recipe in a metric kitchen or halving a recipe in your head, a handful of conversions cover almost everything. Bookmark this page for the tables below.
US volume measures
| Measure | Equals |
|---|---|
| 1 tablespoon | 3 teaspoons (about 15 ml) |

Spoons and pints differ by country
A US tablespoon is about 14.8 ml, a UK or metric tablespoon is 15 ml, and an Australian tablespoon is 20 ml. A teaspoon is about 5 ml almost everywhere. A US pint is 473 ml, but an imperial (UK) pint is 568 ml, so check where a recipe comes from.
Butter
One US stick of butter is 8 tablespoons, which is 1/2 cup or about 113 g. Two sticks make a cup, about 227 g.
Oven temperatures
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. Recipes usually round the result, so you will see these pairings:
| Fahrenheit | Celsius (rounded) |
|---|---|
| 300°F | 150°C |
| 325°F | 160 to 165°C |
| 350°F | 175 to 180°C |
| 375°F | 190°C |
| 400°F | 200°C |
| 425°F | 220°C |
| 450°F | 230°C |
Fan or convection ovens usually need a setting about 20°C (25°F) lower than a conventional oven, so follow your oven's manual.
Volume versus weight
Volume measures like cups and tablespoons cannot be converted to grams without knowing the ingredient. Our cups to grams guide covers that.
