Measuring 150g of Dark Brown Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of dark brown sugar weighs 213g when measured firmly packed, 150 Grams (150g) translates to 0.70 US cups (⅔ cup + 1 ¾ tsp). By contrast, using the unpacked / loose measure (150g/cup — a 63g per-cup shift), 150g occupies 1 cup (1.00 cups).

Without a kitchen scale, measure ⅔ cup + 1 ¾ tsp (11.27 tablespoons total) using firmly packed technique. Pack firmly into the measuring cup to press out all air pockets. Dark brown sugar contains approximately 6.5% molasses, making it denser and stickier than light brown sugar.
