Measuring step this site recommends: spooned and leveled.
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
- Cake flour is finely milled and easy to compact, so the measurement method changes the result substantially.
- Aerate, spoon, and level it; do not dip the cup into the bag for this conversion.
- Bleached, unbleached, and homemade cake-flour blends can have different bulk densities.
- The adopted value is King Arthur's figure for its Unbleached Cake Flour; bleached or extra-fine cake flours can weigh noticeably more or less per cup.
Common mistakes
- Assuming 1 cup of cake flour equals 240g like water — it is actually 120g per US cup.
- Reading “1 cup sifted cake flour” as “1 cup cake flour, sifted”: sifting before measuring puts less flour in the cup.

Frequently asked questions
How many cups is 100 grams of cake flour?
100 grams of cake flour is about 0.83 cups, based on 1 US cup (240 ml) = 120g.
How many grams are in 1 cup of cake flour?
1 US cup of unsifted cake flour weighs about 120 grams when fluffed up, spooned into the cup and leveled.
Does 1 cup of cake 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 cake flour is about 125g, compared with 120g in a US cup.
What's the best way to measure cake flour accurately?
Fluff up the cake flour, spoon it into the cup without sifting and level it off. Use a kitchen scale when your recipe calls for a precise weight.
Can I convert cups of cake flour back to grams?
Yes, use the Cups to Grams tool with cake flour selected to convert any cup amount back into grams.
Why does cake flour convert differently from other ingredients?
Grams measure weight and cups measure volume, so the conversion depends on how dense cake flour is. A denser or lighter ingredient weighs a different amount per cup.
