Convert cups to grams and back for flour, sugar, butter and more — by ingredient.
120
Converting cups to grams is not a fixed number — it depends on the ingredient's density. A cup of flour is about 120 g, but a cup of sugar is about 200 g, and a cup of honey is 340 g. Generic converters can't account for this difference. This tool lets you pick your ingredient and gets the density right, so you can confidently scale recipes between volume and weight.
1 cup of all-purpose flour converts to 120 g — perfect for baking calculations.
1 cup of honey is 340 g, far heavier than flour, because honey is much denser.
240 g of flour converts back to exactly 2 cups.
How many grams is a cup of flour?
All-purpose flour weighs about 120 g per cup. This is the standard used by most baking recipes.
Why isn't cups-to-grams the same for every ingredient?
Different ingredients have different densities. Sugar, honey, and butter all pack differently into a cup, so the gram weight varies.
How many grams in a cup of sugar?
Granulated sugar weighs about 200 g per cup, making it heavier than flour but lighter than honey.
