Cups → Grams Converter

Recipes from different countries use different units. Pick your ingredient, type a number, get the conversion. We use density-accurate ratios so a cup of flour gets a different gram value than a cup of sugar.

Why density matters

A cup is a volume measurement. A gram is a weight measurement. Different ingredients pack different amounts of weight into the same volume. A cup of all-purpose flour weighs about 125g. A cup of granulated sugar weighs about 200g. A cup of honey weighs 340g.

That's why “a cup of flour” in an American recipe doesn't map to one fixed gram value. Pick the actual ingredient and we use its real-world density. The numbers below come from USDA FoodData Central and standard pastry references.

Tip for bakers

Volume measurements are inconsistent. A “packed” cup of brown sugar can weigh 30% more than a lightly scooped one. If a recipe gives both, always use the gram weight. Your bakes will be more consistent.
