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.

Common mistakes

  • Not measuring cake flour the recommended way — spooned and leveled — is one of the most common sources of error.
  • Assuming 1 cup of cake 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.

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 cake flour is about 120 grams, measured spooned 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?

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 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 cup of cake 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.
