Flour Grams to Cups
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.

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:
| Type | 1 cup | vs flour |
|---|---|---|
| All-Purpose Flour | 125g | — |
| Bread Flour | 127g | +2g |
| Cake Flour | 114g | -11g |
| Whole Wheat Flour | 120g | -5g |
| Almond Flour | 96g | -29g |
| Coconut Flour | 128g | +3g |
| Rye Flour | 102g | -23g |
| Self-Rising Flour | 125g | same |
| Semolina Flour | 167g | +42g |
| Buckwheat Flour | 120g | -5g |
| Oat Flour | 104g | -21g |
| Spelt Flour | 120g | -5g |
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 first has the opposite effect and can leave as little as 106g. 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.

Frequently Asked 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.
