Measuring 8 oz of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 8 Ounces (226.8g) translates to 1.77 US cups (1 ¾ cups + 1 tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 8 oz occupies 1 ½ cups + 1 tbsp (1.56 cups).
Without a kitchen scale, measure 1 ¾ cups + 1 tsp (28.35 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.
