How to calculate

Converts grams to cups and back for a baking ingredient, with USDA weights for one level US cup.

Example with the default inputs (Grams (g) 250, Ingredient All-purpose flour (125 g per cup)): 250 g = 2 cup.

Formula: cups = grams ÷ grams per cup, where grams per cup depends on the ingredient (all-purpose flour: 125 g).

  • Grams per cup are USDA FoodData Central (SR Legacy) portion weights for one level US cup (8 US fluid ounces): all-purpose flour 125 g (FDC 168894), granulated sugar 200 g (FDC 169655), brown sugar, packed 220 g (FDC 168833), powdered sugar, unsifted 120 g (FDC 169656).
  • How you fill the cup changes the weight: packed, sifted, or scooped flour can differ by 20% or more.
  • The answer shows at most 6 decimal places; the calculation keeps full precision.

How many cups are in 100 grams?

It depends on the ingredient, because a cup measures volume and a gram measures weight. One level US cup weighs: all-purpose flour 125 g, granulated sugar 200 g, brown sugar, packed 220 g, powdered sugar, unsifted 120 g (USDA).

How do I convert grams to cups?

cups = grams ÷ grams per cup, where grams per cup depends on the ingredient (all-purpose flour: 125 g). For example, 250 g of all-purpose flour is 250 ÷ 125 = 2 cups.

Why does my cup of flour weigh a different amount?

Flour packs down. Spooned and levelled flour weighs about 125 g a cup, but a scooped or packed cup can weigh 20% more. For baking, weighing is more accurate than measuring by volume.
