A high-protein wheat flour that builds extra gluten for chewy, well-structured bread. One US cup weighs about 130g — almost exactly the same weight than a cup of all-purpose flour.

A high-protein wheat flour that builds extra gluten for chewy, well-structured bread. It's also commonly labeled "strong flour", "high-gluten flour".
Bread flour belongs to the Flours group on GramToCup, alongside other ingredients measured the same way in most kitchens. It shows up most often in yeast breads, bagels, pizza dough. Its density of 130g per US cup is what this calculator uses to convert between grams and cups automatically — no manual lookup required.
Bread flour is a dry, milled or ground ingredient full of countless tiny air pockets between the particles. That trapped air is why it weighs relatively little for its volume — the exact weight shifts with how finely it's milled and how much it has settled in the container.
A cup of bread flour is almost exactly the same weight than a cup of all-purpose flour (125g/cup), even though both fill the same 1-cup measuring cup.
Common mistake: Scooping the measuring cup directly into the bag, which packs the contents and can add 20g or more per cup.
Spoon bread flour into the measuring cup, then level off the top with a straight edge. Don't scoop directly from the bag — that packs it down and adds extra weight.
When a recipe needs to be exact, weigh it on a kitchen scale instead of using a measuring cup at all — it removes packing and settling from the equation entirely.
Store bread flour in a sealed container — humidity is the main reason the same cup can weigh differently from one day to the next.
100g of bread flour is approximately 0.77 cups, based on a density of 130g per US cup.
1 US cup of bread flour weighs about 130g. Use the calculator above to convert any other amount instantly.
Yes — "strong flour" is another common name for bread flour. The density and conversion values on this page apply either way.
Because cups measure volume and grams measure weight. A cup of bread flour is almost exactly the same weight than a cup of all-purpose flour (125g/cup) because the two ingredients have different densities — see the density explanation above for why.
Spoon bread flour into the measuring cup, then level off the top with a straight edge. Don't scoop directly from the bag — that packs it down and adds extra weight.
They're in the same category, but check the density first: All-purpose flour weighs 125g per cup versus 130g for bread flour. Substituting by weight (grams) keeps a recipe accurate; substituting cup-for-cup can change the result if the densities differ much.
