One cup of all-purpose flour weighs 125 grams when measured with the spoon-and-level method. Flour is the ingredient where volume measuring goes wrong most often — scooping straight from the bag packs the flour and can add 30% more than the recipe intends.

To measure flour by cups accurately: fluff the flour, spoon it into the cup without packing, and level the top with a straight edge. Different flours differ too — cake flour is lighter (about 114g per cup), while whole wheat flour is about 120g per US cup. Sifted cups can be lighter, while scooped or packed cups can be heavier. For consistent baking, a kitchen scale beats any cup.

Why a cup of flour is not always 125g

Scooping the cup straight into the bag compresses the flour and can pack up to 163g into the same "1 cup" — about 30% more than the recipe intends. Sifting it into the cup has the opposite effect: a sifted cup weighs about 115g. Spoon it in loosely and level the top with a straight edge, and a cup lands near 125g. In a recipe calling for four cups, the difference between scooped and spooned is around 152g of flour — enough to turn a soft dough stiff.

Results use a US customary cup (236.588ml). Spoon and level dry ingredients unless the ingredient name or recipe specifies packed, sifted, melted, chopped, or another condition. Brand, humidity, packing, and measuring technique can change a volume-based result. Reviewed August 15, 2026 against USDA FoodData Central and King Arthur Baking Ingredient Weight Chart.

Flours compared by cup weight

Swapping one type for another changes the weight of a cup, so a recipe written in cups is not portable between them:

Flours: grams per cup, compared with flour
Type	1 cup	vs flour
All-Purpose Flour	125 g	—
All-Purpose Flour (Sifted)	115 g	-10g
Bread Flour	127 g	+2g
Cake Flour	114 g	-11g
Whole Wheat Flour	120 g	-5g
Almond Flour	96 g	-29g
Coconut Flour	128 g	+3g
Rye Flour	102 g	-23g

Questions

How many cups is 100g of flour?

100 grams of all-purpose flour is 0.8 cup — just over ¾ cup. In practice: ¾ cup plus 1 tablespoon gets you very close.

Is 1 cup of flour 120g or 125g?

Both appear in cookbooks. King Arthur uses 120g per cup; most other US sources use 125g (the value this site uses). The real-world variation in how people fill a cup is bigger than that 5g difference — which is exactly why weighing wins.

How many cups is 500g of flour?

500 grams of all-purpose flour is 4 cups exactly (at 125g per cup).

Why does scooping flour from the bag give too much?

Pushing the cup into the bag compresses the flour, packing up to 150g or more into a "1 cup" measure instead of 125g. Spoon the flour into the cup loosely and level it off instead.

Do bread flour and cake flour weigh the same per cup?

Close but not identical: bread flour is about 127g per cup, cake flour about 114g because it is more finely milled. All-purpose sits in the middle at 125g.
