Why a cup of flour is not a cup of sugar
A cup measures volume, a gram measures weight. A cup of all-purpose flour weighs about 120 g, but a cup of granulated sugar about 198 g and a cup of honey about 336 g, because they have different densities. So there is no single cups-to-grams number: choose the ingredient first. Weighing is also more accurate, because a cup of flour can vary by 30 g or more depending on how it is filled.
Common conversions (US cup)
- 1 cup all-purpose flour = 120 g · 1 cup whole wheat flour = 113 g
- 1 cup granulated sugar = 198 g · 1 cup packed brown sugar = 213 g · 1 cup powdered sugar = 113 g
- 1 cup butter = 227 g (2 sticks; 1 stick = 113 g, 8 tablespoons)
- 1 cup water = 237 g · 1 cup milk ≈ 242 g · 1 cup oil ≈ 218 g
- 1 cup rolled oats = 89 g · 1 cup cocoa powder = 84 g · 1 cup chocolate chips = 170 g
Measuring tips
- Flour values assume the spoon-and-level method: spoon flour into the cup and sweep off the top. Scooping straight from the bag packs in up to 20% more.
- Australian, New Zealand and many Indian recipes use a 250 ml metric cup; older British recipes may use a 284 ml cup. Pick the cup size to match the recipe.
- A US tablespoon is 14.8 ml and a teaspoon 4.9 ml; metric spoons are 15 and 5 ml. Australian tablespoons are 20 ml.
- Values are typical averages for baking. Brands and humidity vary, so treat them as close guides rather than lab measurements.
