Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Powdered sugar (confectioners sugar, icing sugar) is much lighter than granulated. 1 cup unsifted = 120g. Sifted: ~100g. Always sift before using to remove lumps. Used for frosting, dusting, and recipes requiring smooth texture.
About Powdered Sugar Density
The density of powdered sugar determines how much it weighs per unit of volume. At 0.5g/ml, 1 US cup (240ml) of powdered sugar weighs 120g under USDA standard conditions.
1 teaspoon = 1/48 cup = 5ml. For powdered sugar, this equals 2.5g per teaspoon. Teaspoon measurements are critical for spices, extracts, and leavening agents where small differences have large effects. A kitchen scale is especially recommended for teaspoon-level precision.
