How to measure 1 cup of powdered sugar

By weight (most accurate): set your bowl on a kitchen scale, press tare, and add 120 g of powdered sugar.

By volume: Use a 1-cup measure, or 16 tablespoons.

Powdered (confectioners’) sugar is fine and airy, so a cup weighs far less than a cup of granulated sugar. Sift it if the recipe says “sifted”.

Why powdered sugar weighs what it does

Powdered sugar is about 49% lighter than the same volume of water, which weighs about 237 g per cup. That is why you can't convert cups to grams without knowing the ingredient.
