Measuring 450g of Self-Rising Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of self-rising flour weighs 113g when measured spooned & leveled, 450 Grams (450g) translates to 3.98 US cups (3 ¾ cups + 3 tbsp + 2 ¼ tsp). By contrast, using the dip scooped measure (135g/cup — a 22g per-cup shift), 450g occupies 3 ⅓ cups (3.33 cups).
Without a kitchen scale, measure 3 ¾ cups + 3 tbsp + 2 ¼ tsp (63.72 tablespoons total) using spooned & leveled technique. Whisk briefly to evenly disperse the baking powder and salt before spooning into the measuring cup.
