Measuring 16 oz (1 lb) of Bread Flour in the Kitchen

Because 1 US Customary Cup (236.6 mL) of bread flour weighs 127g when measured spooned & leveled, 16 Ounces (453.6g) translates to 3.57 US cups (3 ½ cups + 1 tbsp + ½ tsp). By contrast, using the scooped from bag measure (148g/cup — a 21g per-cup shift), 16 oz occupies 3 cups + 1 tbsp (3.06 cups).

Without a kitchen scale, measure 3 ½ cups + 1 tbsp + ½ tsp (57.15 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.
