Convert grams to cups for common baking ingredients using their typical densities.
Usage Tip
For accuracy in baking, weigh ingredients in grams rather than converting to cups.
Why grams to cups depends on the ingredient
100 g of flour is not 100 g of sugar. Different ingredients have different densities, so the same weight takes up a different volume – which is why this converter asks you to pick the ingredient first.

Common grams to cups conversions
100 grams to cups
100 grams is about 0.8 cup of flour, 0.5 cup of white sugar, or 0.44 cup of butter. Light, fluffy ingredients fill more of a cup per 100 g; dense ones fill less.
200 grams to cups
200 grams is about 1.6 cups of flour, exactly 1 cup of white sugar, or about 0.88 cup of butter.
250 grams to cups
250 grams is about 2 cups of flour, 1.25 cups of sugar, or roughly 1.1 cups of butter. A quarter-kilo of flour is a very common recipe amount.
500 grams to cups
500 grams is about 4 cups of flour, 2.5 cups of sugar, or about 2.2 cups of butter. Half a kilo of flour is a typical bread-recipe quantity.

Worked example
One US cup of all-purpose flour is about 120 g, so 300 g is 300 ÷ 120 = 2.5 cups. A cup of sugar is about 200 g, a cup of water is about 237 g and a cup of butter is about 227 g.
Common mistakes
Grams-per-cup values depend on the ingredient and on how it is packed: scooping flour with the cup can put 140 g or more in it, which is why weighing is more consistent. Always check which cup size (US, metric or imperial) a recipe uses.
