Measuring 150g 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, 150 Grams (150g) translates to 0.75 US cups (¾ cup). By contrast, using the loosely spooned (unpacked) measure (145g/cup — a 55g per-cup shift), 150g occupies 1 cup + 1 ¾ tsp (1.03 cups).

Without a kitchen scale, measure ¾ cup (12 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.
