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 can pack the cup and add up to 25% more weight.
- Use a kitchen scale for the most accurate baking results.
Common mistakes
- Not measuring all-purpose flour the recommended way — spooned and leveled — is one of the most common sources of error.
- Assuming 1 cup of all-purpose flour equals 240g like water — it is actually 120g per US cup.
- Scooping the cup straight into the bag, which packs the ingredient and can add up to 25% extra weight.

How many grams are in 1 cup of all-purpose flour?
1 US cup of all-purpose flour is about 120 grams, measured spooned 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?
For the most accurate result, spooned and leveled, and 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 cup of all-purpose flour weighs 120g, while a denser or lighter ingredient weighs a different amount per cup.
Where do these numbers come from?
See how we measure ingredient density and verify each grams-per-cup value.
