US cups to millilitres
| US cups | Millilitres |
|---|---|
| 1/8 cup | 30 ml |
| 1/4 cup | 59 ml |
| 1/3 cup | 79 ml |
| 1/2 cup | 118 ml |
| 2/3 cup | 158 ml |
| 3/4 cup | 177 ml |
| 1 cup | 237 ml |
| 1 1/4 cups | 296 ml |
| 1 1/2 cups | 355 ml |
| 2 cups | 473 ml |
| 3 cups | 710 ml |
| 4 cups | 946 ml |
A metric cup (used in Australia, New Zealand and Canada) is 250 ml, slightly more than a US cup. For most recipes the difference doesn't matter; for baking it can.
Spoons, fluid ounces, pints and quarts
| US measure | Millilitres |
|---|---|
| 1/4 teaspoon | 1.2 ml |
| 1/2 teaspoon | 2.5 ml |
| 1 teaspoon | 4.9 ml |
| 1/2 tablespoon | 7.4 ml |
| 1 tablespoon | 15 ml |
| 2 tablespoons | 30 ml |
| 1 fluid ounce | 30 ml |
| 1 pint | 473 ml |
| 1 quart | 946 ml |
| 1 gallon | 3785 ml |
Ounces and pounds to grams
| US weight | Grams |
|---|---|
| 1 ounce (oz) | 28 g |
| 4 oz | 113 g |
| 8 oz | 227 g |
| 1 pound (lb) | 454 g |
| 2 lb | 907 g |
Watch out for fluid ounces (volume, 29.6 ml) versus ounces (weight, 28.3 g). A recipe that says "8 oz cheese" means weight; "8 fl oz milk" means volume.
Oven temperatures, °F to °C
| Fahrenheit | Celsius |
|---|---|
| 300 °F | 149 °C |
| 325 °F | 163 °C |
| 350 °F | 177 °C |
| 375 °F | 191 °C |
| 400 °F | 204 °C |
| 425 °F | 218 °C |
| 450 °F | 232 °C |
For a fan (convection) oven, many cooks go about 20 °C lower.
Why cups don't convert neatly to grams
A cup measures volume, not weight. A cup of flour weighs far less than a cup of sugar, and how you fill the cup changes it too. That's why Table converts cups, spoons and fluid ounces to millilitres, and ounces and pounds to grams, but never guesses a weight from a volume.
Convert a whole recipe at once
Save any US recipe to Table, from a website, Instagram or TikTok, and the ingredients are converted to metric when you import it. One tap switches the recipe between metric and US units, and changing the servings recalculates every quantity.
