Measuring 400g of Oat Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of oat flour weighs 92g when measured spooned & leveled, 400 Grams (400g) translates to 4.35 US cups (4 ⅓ cups). By contrast, using the scooped from bag measure (104g/cup — a 12g per-cup shift), 400g occupies 3 ¾ cups + 1 tbsp + 1 ½ tsp (3.85 cups).
Without a kitchen scale, measure 4 ⅓ cups (69.57 tablespoons total) using spooned & leveled technique. Spoon lightly and level. Oat flour is exceptionally light and fluffy; shaking the cup causes severe settling.
