In practice
Powdered sugar (icing sugar in the UK) is granulated sugar ground to a fine powder, usually with a little cornstarch to stop caking. It is very light, so a cup weighs only about 120 g — far less than a cup of granulated sugar. Sift it before measuring or using, since it packs and clumps easily. It dissolves instantly, which is why it is used for icings, glazes and dusting, but it will not give the same texture as granulated sugar if swapped into a cake recipe.
How to convert cups of powdered sugar to grams
