1 Cup Brown sugar in Grams
1 cup of brown sugar weighs:
220 g
US cup (240 ml)
229 g
Metric / AU cup (250 ml)
American recipes mean the 240 ml cup; Australian, British and New Zealand recipes mean the 250 ml metric cup. If the recipe does not say, the cuisine usually tells you — see the full cups to grams guide.
Brown sugar is measured packed — pressed firmly into the cup so it holds the shape when tipped out. Packed, a cup is about 220 g. Loose, the same cup might hold only 145 g, which is why recipes are explicit about it.

Frequently asked questions
How many grams is 1 cup of brown sugar?
1 US cup of brown sugar is 220 g. In an Australian, UK or NZ metric cup (250 ml) it is 229 g. Weighing is more accurate than measuring by volume.
How many grams is half a cup of brown sugar?
Half a US cup of brown sugar is 110 g, and three-quarters of a cup is 165 g.
What does "firmly packed" brown sugar mean?
Press the sugar into the cup with the back of a spoon until it is compacted, then level the top. Tipped out, it should hold the shape of the cup. Unless a recipe says otherwise, packed is the default for brown sugar.
Is light and dark brown sugar the same weight?
Yes, both are about 220 g per packed cup. Dark brown sugar has more molasses, which changes the flavour and colour but not the packing density in any meaningful way.
Can I substitute white sugar for brown sugar by weight?
By weight, yes — use the same gram figure. But you lose the molasses, which contributes moisture and acidity. Adding a tablespoon of molasses per 200 g of white sugar recreates it closely.
