Measuring 4 oz of Light Brown Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of light brown sugar weighs 200g when measured firmly packed, 4 Ounces (113.4g) translates to 0.57 US cups (½ cup + 1 tbsp + ¼ tsp). By contrast, using the loosely spooned (unpacked) measure (145g/cup — a 55g per-cup shift), 4 oz occupies ¾ cup + 1 ½ tsp (0.78 cups).

Without a kitchen scale, measure ½ cup + 1 tbsp + ¼ tsp (9.07 tablespoons total) using firmly packed technique. Press sugar firmly into the dry measuring cup with your fingers or a spoon until it holds the shape of the cup when inverted.
