Measuring 450g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 450 Grams (450g) translates to 3.52 US cups (3 ½ cups). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 450g occupies 3 cups + 1 tbsp + 2 tsp (3.10 cups).
Without a kitchen scale, measure 3 ½ cups (56.25 tablespoons total) using spooned & leveled technique. Cornstarch packs easily into a solid cake when pressed; scoop gently with a spoon and sweep level with a straightedge.
