Convert Cups to Grams: Brown Sugar (packed)
Convert cups of brown sugar (packed) to grams with this complete reference table. 1 cup of brown sugar (packed) = 220g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because brown sugar (packed) density can vary by measuring technique.

| Cups | Grams |
|---|---|
| 1/8 cup | 27.5g |
| 1/4 cup | 55g |
| 1/3 cup | 73.3g |
| 1/2 cup | 110g |
| 2/3 cup | 146.7g |
| 3/4 cup | 165g |
| 1 cup | 220g |
| 1 1/4 cups | 275g |
| 1 1/2 cups | 330g |
| 2 cups | 440g |
| 3 cups | 660g |
| 4 cups | 880g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Brown sugar is almost always measured packed. Press firmly into the cup — it should hold its shape when turned out. 1 cup packed = 220g. Light brown: ~200g. Dark brown: ~220g. The molasses coating makes it sticky and dense.
About Brown Sugar (packed) Density
The density of brown sugar (packed) determines how much it weighs per unit of volume. At 0.917g/ml, 1 US cup (240ml) of brown sugar (packed) weighs 220g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
