FAQ

How many grams are in a cup?

It depends on what is in the cup: a cup is a volume, and each ingredient packs a different weight into it. A US cup holds 125 grams of all-purpose flour, 200 grams of granulated sugar, 227 grams of butter and 236.6 grams of water.

How many grams is 1/2 cup of butter?

113.5 grams — half of the 227 grams a full US cup of butter weighs, which is one standard US stick of butter.

How do you convert cups to grams?

Multiply the cups by the weight of one cup of that ingredient. For 2 1/2 cups of flour that is 2.5 × 125 = 312.5 grams. Fractions work the same way: 1/3 cup is a third of the cup weight.

Why does my recipe give a different weight for a cup of flour?

Because flour is scooped, and how it is scooped changes the weight. This page uses the USDA figure of 125 grams per cup; King Arthur Baking uses 120 g for flour spooned in lightly, and flour packed down weighs more. For baking, weighing is always more exact than a cup.
