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.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
