1 Cup in Grams
1 cup weighs 120 grams of all-purpose flour, 200 grams of granulated sugar, or 227 grams of butter — a cup is a volume, so the weight always depends on what's in it. Find your ingredient below; densities verified against King Arthur and USDA data.

Why there's no single answer
Grams measure weight; cups measure volume. 1 cup of feather-light powdered sugar (120 g) and 1 cup of dense honey (340 g) fill the same cup at nearly a 3× weight difference. Recipes that list grams remove that ambiguity — which is why serious baking recipes weigh.
