When sources disagree, follow your recipe: use its gram weights if it gives them, or measure the way its author did. The adopted value is one stated convention, not a correction of the other sources.
A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
Measurement notes
- Flour weight varies by scooping, spooning, sifting, humidity, and brand.
- Spoon flour into the cup and level with a knife — do not scoop.
- Scooping packs the flour, so the cup ends up noticeably heavier.
- Use a kitchen scale for the most accurate baking results.
Common mistakes
- Assuming 1 cup of all-purpose flour equals 240g like water — it is actually 120g per US cup.
- Using this cup weight for almond flour, which weighs less per cup than wheat flour.

Frequently asked questions
How many cups is 100 grams of all-purpose flour?
100 grams of all-purpose flour is about 0.83 cups, based on 1 US cup (240 ml) = 120g.
How many grams are in 1 cup of all-purpose flour?
1 US cup of unsifted all-purpose flour weighs about 120 grams when spooned into the cup and leveled.
Does 1 cup of all-purpose flour weigh the same in a metric cup?
No. A metric cup (250 ml) holds slightly more than a US cup (240 ml), so 1 metric cup of all-purpose flour is about 125g, compared with 120g in a US cup.
What's the best way to measure all-purpose flour accurately?
Spoon unsifted flour into the cup and level it off. Use a kitchen scale when your recipe calls for a precise weight.
Can I convert cups of all-purpose flour back to grams?
Yes, use the Cups to Grams tool with all-purpose flour selected to convert any cup amount back into grams.
Why does all-purpose flour convert differently from other ingredients?
Grams measure weight and cups measure volume, so the conversion depends on how dense all-purpose flour is. A denser or lighter ingredient weighs a different amount per cup.
