## How to Convert Cups to Grams ### Formula **Grams = Cups x Density (g/cup)** Cup-to-gram conversions depend on the ingredient because each ingredient has a different density. Flour is much lighter per cup than sugar or butter. ### Why Weight Matters in Baking Measuring by weight is more accurate than measuring by volume. A cup of flour can vary by 30 g depending on how it is scooped.
计算示例
Convert 2 cups of all-purpose flour to grams.
- 01Identify the density of all-purpose flour: 125 g per cup.
- 02Multiply: 2 cups x 125 g/cup = 250 g.
- 03The result is 250 grams of flour.
常见问题
Why does 1 cup of flour weigh less than 1 cup of sugar?
Flour has lower density than sugar. Flour particles trap more air, so the same volume weighs less. One cup of flour is about 125 g while one cup of sugar is about 200 g.
Should I sift flour before measuring?
If measuring by cups, the spoon-and-level method is recommended: spoon flour into the cup and level off with a knife. Sifting first gives a lighter cup. For accuracy, use a kitchen scale.
Are metric cups the same as US cups?
