Working with powdered sugar
Powdered Sugar sits in the sugars & syrups group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. Unsifted powdered sugar traps lumps and air. Sifted it measures around 112 g per cup.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
Also sold as: confectioners sugar, icing sugar. These names refer to the same product and use the same weight per cup.
