Calculation & Mathematical Derivation
To convert 30 grams of Powdered Sugar (Confectioners / Icing Sugar) into US Customary measuring cups (236.6 mL):
Cups = Weight in Grams ÷ Grams per Cup (Bulk Density)Cups = 30g ÷ 120g/cup = 0.25 cups (kitchen fraction: 1/4 cups)Tablespoons = 30g ÷ 7.50g/tbsp = 4.0 tablespoonsThis calculation is calibrated specifically for Spooned and leveled (unsifted) under standard kitchen conditions (sourced from USDA FoodData Central (FDC ID 169656)).
Technique Note: Unsifted powdered sugar weighs ~120g/cup; sifted powdered sugar weighs ~100g/cup.
