Exact Formula

Calculation & Mathematical Derivation

To convert 115 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 = 115g ÷ 120g/cup = 0.96 cups (kitchen fraction: 1 cups)

Tablespoons = 115g ÷ 7.50g/tbsp = 15.3 tablespoons

This 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.
