How many cups is 200 grams of caster sugar?
200 g of caster sugar ≈ 1.05 cups
One US cup of caster sugar weighs about 190 grams, so 200 grams works out to roughly 1.05 cups. Caster (superfine) sugar has smaller crystals than granulated sugar, so it settles a little lighter.
200 g is a common recipe quantity, but cups measure volume, not weight. For the most reliable result, weigh caster sugar with a kitchen scale rather than scooping — see why weighing wins.
