This is based on 1 cup of powdered sugar = 120 g, so 1/3 cup of powdered sugar is 1/3 × 120 ≈ 40 g.
How to measure 1/3 cup of powdered sugar
By weight (most accurate): set your bowl on a kitchen scale, press tare, and add 40 g of powdered sugar.
By volume: Use a 1/3-cup measure, or 5 tablespoons plus 1 teaspoon.
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.
