Measuring 400g of Bread Flour in the Kitchen

Because 1 US Customary Cup (236.6 mL) of bread flour weighs 127g when measured spooned & leveled, 400 Grams (400g) translates to 3.15 US cups (3 cups + 2 tbsp + 1 ¼ tsp). By contrast, using the scooped from bag measure (148g/cup — a 21g per-cup shift), 400g occupies 2 ⅔ cups + 1 ¾ tsp (2.70 cups).

Without a kitchen scale, measure 3 cups + 2 tbsp + 1 ¼ tsp (50.39 tablespoons total) using spooned & leveled technique. Spoon into cup and level flat. Its 12-14% protein content yields dense granules that settle rapidly during storage.
