Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of bread flour weighs about 4.48 oz. Why these two are not the same.
In grams, 1/4 cup of bread flour is about 32 g, 1/3 cup is about 42 g, 1/2 cup is about 64 g, 2/3 cup is about 85 g, 3/4 cup is about 95 g, 1 cup is about 127 g, 1 1/2 cups is about 191 g, 2 cups is about 254 g and 3 cups is about 381 g.
A tablespoon of bread flour is about 7.9 grams, and a teaspoon is about 2.6 grams.
About measuring bread flour
Bread flour has a higher protein content than all-purpose flour, which gives loaves their chew and structure. One US cup weighs roughly 127 grams, just a hair heavier than all-purpose. In bread baking, small differences in flour weight change the hydration of your dough, so a scale is your best friend here. A dough that felt too sticky last time is often just a cup of flour measured a little light.
For consistent hydration in bread doughs, always weigh your flour rather than scooping.
How many grams is a cup of bread flour?
One US cup (240 ml) of bread flour weighs about 127 grams. Because a cup measures volume rather than weight, that figure is specific to bread flour and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of bread flour is about 32 grams
- 1/3 cup of bread flour is about 42 grams

Working the other way round, 100 grams of bread flour is about 0.787 cups, and 500 grams is about 3.94 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of bread flour comes to about 132 grams, and the old British imperial cup of 284.1 ml holds about 150 grams.

Frequently asked questions
How many grams is 1 cup of bread flour?
One US cup of bread flour is about 127 grams. It is marginally denser than all-purpose flour because of its higher protein content.
Can I swap bread flour for all-purpose by weight?
Yes. Because their weights per cup are so close, you can substitute gram for gram. The result will simply be a little chewier with bread flour.
Does bread flour need more water?
Often yes. Its extra protein absorbs more liquid, so recipes built around bread flour tend to run at a higher hydration than the same recipe with all-purpose.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of bread flour. The 127 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
