Measuring 4 oz of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 4 Ounces (113.4g) translates to 0.89 US cups (¾ cup + 2 tbsp + ½ tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 4 oz occupies ¾ cup + 1 ½ tsp (0.78 cups).
Without a kitchen scale, measure ¾ cup + 2 tbsp + ½ tsp (14.17 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.
