Convert Cups to Grams: Bread Flour

Convert cups of bread flour to grams with this complete reference table. 1 cup of bread flour = 130g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because bread flour density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Bread flour is slightly denser than all-purpose flour due to higher protein content (12-14% vs 10-12%). 1 cup bread flour = 130g (spooned). Higher gluten protein means denser packing. Best for yeast breads, pizza dough.

About Bread Flour Density

The density of bread flour determines how much it weighs per unit of volume. At 0.542g/ml, 1 US cup (240ml) of bread flour weighs 130g under USDA standard conditions.

Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.

Frequently Asked Questions

How many grams is 1 cup of bread flour?

1 cup of bread flour weighs 130 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
