Brown Sugar Grams to Cups Converter & Chart (Packed g to cups)
One US cup of packed brown sugar weighs 220 grams (7.76 oz), while unpacked (loose) brown sugar weighs approximately 145 grams per cup. Because brown sugar contains molasses, it holds significantly more moisture than granulated white sugar (200g/cup), creating sticky air pockets that compress when packed into a measuring cup. Whether baking chewy chocolate chip cookies, caramel glazes, or marinades, use our calculator and complete reference table below to get exact conversions between grams, cups, and tablespoons.

Packed vs. Unpacked: Why Packing Matters for Brown Sugar
Unlike granulated white sugar, which flows freely like dry sand, brown sugar has a thin coating of sticky molasses syrup around each sucrose crystal. This coating causes grains to cling together, creating large air gaps when scooped loosely into a measuring cup.
- Firmly Packed (220g/cup): Pressing the sugar down with the back of a spoon or your fingers expels trapped air, creating consistent, repeatable volume. When inverted, properly packed brown sugar holds the exact shape of the measuring cup.
- Light vs. Dark Brown Sugar: Light brown sugar contains roughly 3.5% molasses, whereas dark brown sugar contains approximately 6.5% molasses. While dark brown sugar has a stronger caramel profile, both light and dark varieties weigh approximately 220 grams per packed cup.
- Weight Accuracy: Weighing on a digital kitchen scale eliminates packing errors, ensuring your cookies achieve their intended chewiness without becoming overly dense or oily.
