Grams to Cups: Light Brown Sugar
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for light brown sugar. One cup of light brown sugar weighs about 213 grams, which works out to a density of 0.90 g/ml. From there, half a cup is roughly 107 g, a quarter cup about 53 g, and one tablespoon about 13 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of light brown sugar does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of light brown sugar rather than a one-size-fits-all figure.

How to measure light brown sugar accurately
For light brown sugar, spoon or pour it into the cup and level the top. Brown sugar is the exception — pack it down firmly into the cup unless the recipe says otherwise, because it traps air and would otherwise come up short on weight.
Weighing in grams removes any doubt about how firmly the sugar is packed, which is especially helpful in delicate recipes.
