Measuring 16 oz (1 lb) of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 16 Ounces (453.6g) translates to 3.54 US cups (3 ½ cups + 2 tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 16 oz occupies 3 ⅛ cups (3.13 cups).
Without a kitchen scale, measure 3 ½ cups + 2 tsp (56.7 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.
