Cups to Grams by Ingredient
Convert cups to grams for specific ingredients with accurate density-based measurements.
Results
Converting cups to grams by ingredient is critical for accurate baking because different ingredients have vastly different densities. One cup of flour weighs 120g while one cup of sugar weighs 200g and one cup of butter weighs 227g. A generic volume-to-weight converter gets this wrong - this tool uses ingredient-specific densities.

Frequently asked questions
1 cup of all-purpose flour weighs approximately 120 grams when spooned and leveled. Scooped flour can weigh up to 150g, which is why weighing is more accurate.
1 cup of granulated sugar weighs approximately 200 grams. Brown sugar weighs about 220g per cup because it packs more densely.
Density varies by ingredient. Flour is light and airy (120 g/cup), sugar is granular and dense (200 g/cup), and butter is solid and heavy (227 g/cup).
1 cup of butter weighs 227 grams (8 ounces or 2 sticks). Butter is one of the densest common baking ingredients.
Professional bakers prefer grams because weight is more precise than volume. Cup measurements can vary by 20% depending on how you scoop, which affects baking results.
