Bread Flour: Grams to Cups
1 cup of bread flour = 130 grams
One US cup of bread flour weighs 130 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 137 grams. To convert any weight, divide the grams by the figure for your cup.
Bread flour weighs about 130 g per cup here. The references split: King Arthur Baking gives 120 g (sprinkled and levelled) and USDA FoodData Central 137 g, because the higher-protein flour packs a little tighter when dipped.
Why bread flour weighs a little more than all-purpose
Bread flour is milled from harder wheat with more protein, typically 12–14% against 10–12% for all-purpose. The particles are slightly coarser and pack more tightly, so a dipped cup comes out heavier — USDA records 137 g for enriched bread flour against 125 g for all-purpose.
King Arthur, which sprinkles flour into the cup, weighs both flours the same at 120 g. The 130 g used here is between the two and is within about 5% of each.
Swapping bread flour and all-purpose
Weight for weight the two swap cleanly; the difference is in how the dough behaves. Bread flour absorbs more water, so a bread dough made with all-purpose will feel slacker — hold back a tablespoon or two of the water. Cakes made with bread flour come out chewier and taller than intended.
If you are converting a recipe that gives bread flour in cups, weigh 130 g per cup unless the recipe says it was written with King Arthur's chart, in which case use 120 g.

How to measure bread flour accurately
The 130 g figure assumes the spooned-and-levelled method: spoon the bread flour into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
- 1 US cup of bread flour = 130 g
- 1 metric cup (250 ml) of bread flour = 137 g
- ¾ cup = 98 g
- ½ cup = 65 g
- ⅓ cup = 43 g
- ¼ cup = 33 g
- 1 tablespoon = 8.1 g
