Grams to Cups: Demerara Sugar
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for demerara sugar. One cup of demerara sugar weighs about 230 grams, which works out to a density of 0.97 g/ml. From there, half a cup is roughly 115 g, a quarter cup about 58 g, and one tablespoon about 14 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of demerara sugar does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of demerara sugar rather than a one-size-fits-all figure.

How to measure demerara sugar accurately
For demerara 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.
