The UK cup is slightly larger than the US cup: 1 UK cup = 10 UK fluid ounces (284 ml vs 237 ml). Most modern British recipes have shifted to metric measurements (ml and grams), so this distinction rarely causes problems in practice, but it's worth knowing when using older British cookbooks.
This is the source of most confusion in volume-weight conversions:
For water, 1 cup happens to be approximately 8.35 oz by weight (because water is denser than exactly 1 fl oz per oz). For flour, 1 cup is about 4.5 oz by weight. For sugar (granulated), 1 cup is about 7 oz by weight.
| Ingredient | 1 Cup Volume | Weight (oz) | Weight (grams) |
|---|---|---|---|
| All-purpose flour | 1 cup | 4.5 oz | 128 g |
| Granulated sugar | 1 cup | 7.1 oz | 200 g |
| Brown sugar (packed) | 1 cup | 7.7 oz | 220 g |
| Powdered sugar | 1 cup | 4 oz | 115 g |
| Butter | 1 cup (2 sticks) | 8 oz | 227 g |
| Rolled oats | 1 cup | 3.2 oz | 90 g |
| Rice (uncooked) | 1 cup | 6.5 oz | 185 g |

1 US cup equals 8 fluid ounces. This is the standard conversion for liquids in US recipes.
8 fluid ounces equals 1 cup. For weight ounces, it depends on the ingredient — water is close to 8 oz per cup, but flour is about 4.5 oz per cup.
1 cup = 16 tablespoons = 48 teaspoons. A quarter cup = 4 tablespoons. A half cup = 8 tablespoons.
1 US cup = 237 ml (approximately 240 ml). 1 UK cup = 284 ml. Metric recipes typically use 250 ml as an approximation of 1 cup.
2 cups = 16 fluid ounces = 1 US pint = 473 ml.
