Sources & how they compare
| Source | Reported value | Comparable source-cup value | Type | Measurement method | Adopted here | Checked |
|---|---|---|---|---|---|---|
| King Arthur Baking — Ingredient Weight Chart | 120 g/1 source cup (exact volume unknown) | 120g | Direct | spooned and leveled | Adopted | 2026-08-05 |
| Bob's Red Mill — Flour Weight Chart | 144 g/1 source cup (exact volume unknown) | 144g | Direct | spooned and leveled | 2026-08-05 |
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
- Bread flour is higher in protein than all-purpose flour, but protein content alone does not fix its cup weight.
- Fluff the flour, spoon it into the cup, and level it without shaking or packing.
- Brand and humidity differences can move a cup well above the adopted 120g convention, so weigh when dough hydration matters.
Common mistakes
- Not measuring bread flour the recommended way — spooned and leveled — is one of the most common sources of error.
- Assuming 1 cup of bread 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.

What's the best way to measure bread 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 bread flour back to grams?
Yes, use the Cups to Grams tool with bread flour selected to convert any cup amount back into grams.
Why does bread flour convert differently from other ingredients?
Grams measure weight and cups measure volume, so the conversion depends on how dense bread flour is. A cup of bread flour weighs 120g, while a denser or lighter ingredient weighs a different amount per cup.
