Brown sugar:
grams to cups.
Brown sugar weighs 213 g per cup when packed — the standard method specified in virtually every recipe. Unlike granulated sugar, brown sugar clumps and will not fill a cup uniformly without packing, making it one of the most inconsistently measured ingredients in home baking.

The "packed" convention and what it actually means
When a recipe says "1 cup brown sugar, packed," it means you press the sugar firmly into the measuring cup until the surface is level and the sugar holds its shape when turned out. The packing removes air pockets that would otherwise reduce the weight per cup by 20–30%. An unpacked cup of brown sugar may weigh only 150–160 g, versus 213 g when properly packed. This is why "packed" is not optional — it is a density specification embedded in the cup measurement. The 213 g/cup figure reflects properly packed brown sugar. If your recipe doesn't say "packed" but it's a cookie or cake recipe, packed is almost certainly what was intended.
Molasses content and why different browns measure differently
Brown sugar is white granulated sugar with molasses added back in after refining. Light brown sugar contains about 3.5% molasses; dark brown sugar contains about 6.5%. The extra molasses in dark brown sugar slightly increases its density and moisture content, meaning a packed cup of dark brown sugar may weigh a few grams more than light brown. For most recipes this difference is negligible, but for confectionery where precise moisture content affects caramelization and final texture, weighing rather than packing ensures you're adding exactly the right amount of molasses-rich sugar.
Frequently asked questions
- How many grams is 1 cup of brown sugar packed?
- 1 cup of packed brown sugar weighs 213 g. Unpacked, the same cup may weigh only 150–160 g — a significant difference.
- How many cups is 250 g of brown sugar?
- 250 g ÷ 213 g/cup ≈ 1.17 cups — just over 1 cup and 2-3 tablespoons.
- Does dark brown sugar weigh the same as light brown sugar?
- Nearly the same. Dark brown sugar has slightly more molasses, which adds marginal moisture and density, but the difference is typically 2–5 g per cup — within the margin of normal packing variation.
Common substitutions
| Substitute for brown sugar | Ratio | Notes |
|---|---|---|
| Granulated sugar | 1:1 by weight | Omits molasses flavour and moisture. Baked goods will be slightly less chewy and lighter in colour. |
| Coconut sugar | 1:1 by weight | Similar molasses notes, slightly less sweet. Dissolves less readily — best for cookies and bars, not sauces. |
| Muscovado sugar | 1:1 by weight | Higher molasses content than brown sugar; deeper, more intense flavour. Direct swap in weight. |
