| USDA FoodData Central — Sugars, brown (FDC 168833)FDC ID: 168833Backup mirror reference: nutritionvalue.org mirror (backup reference) | 220 g/1 source cup, packed (exact volume unknown) | 220g | Direct | firmly packed | Adopted | 2026-08-04 |

A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
Measurement notes
- Brown sugar must be firmly packed into the measuring cup — packed versus loose can change the weight by a large margin.
- It should hold the shape of the cup when turned out, which confirms it was packed correctly.
- Light and dark brown sugar have nearly the same density, since the difference is mostly molasses color and flavor, not weight.
- Brown sugar hardens when exposed to air, so measure it soon after opening for a more consistent result.
Common mistakes
- Not measuring brown sugar (packed) the recommended way — firmly packed — is one of the most common sources of error.
- Assuming 1 cup of brown sugar (packed) equals 240g like water — it is actually 220g per US cup.
- Assuming every type of sugar (granulated, brown, powdered) weighs the same per cup.

Can I convert cups of brown sugar (packed) back to grams?
Yes, use the Cups to Grams tool with brown sugar (packed) selected to convert any cup amount back into grams.
Why does brown sugar (packed) convert differently from other ingredients?
Grams measure weight and cups measure volume, so the conversion depends on how dense brown sugar (packed) is. A cup of brown sugar (packed) weighs 220g, while a denser or lighter ingredient weighs a different amount per cup.
Where do these numbers come from?
