Measuring 450g 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, 450 Grams (450g) translates to 2.25 US cups (2 ¼ cups). By contrast, using the loosely spooned (unpacked) measure (145g/cup — a 55g per-cup shift), 450g occupies 3 cups + 1 tbsp + 2 tsp (3.10 cups).

Without a kitchen scale, measure 2 ¼ cups (36 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.
