How many grams are in a cup of sugar?
One US cup of sugar is about 201 g, or 7.1 oz. To convert other amounts, multiply the number of cups by 201: half a cup is 101 g and a quarter of a cup is 50 g. The converter above does it for any amount and also shows the result in ounces.

About sugar
White granulated sugar weighs about 201 g per cup in this converter, in line with the 200 g used in most recipes. Caster sugar is very close, while icing sugar is much lighter and brown sugar heavier when packed.
Baking tip
Sugar affects more than sweetness: it keeps cakes moist, helps browning and gives structure to meringues. Measuring it by weight keeps results the same from one batch to the next.
