Ingredient Weight Calculator
Convert cups to grams and grams to cups for specific ingredients with accurate density-based measurements.
Results
Converting between cups and grams requires knowing the ingredient because densities vary widely. One cup of flour weighs 120g while one cup of sugar weighs 200g - a generic volume converter gets this wrong. Professional bakers always weigh ingredients in grams because it is more precise than volume measurement. This calculator covers 20+ common baking ingredients with accurate density data.
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.
