How Much Is 10.58 Ounces of Powdered Sugar in Cups?
10.58 ounces of powdered sugar equals 2.50 cups. Powdered sugar has a density of 120g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 10.58 ounces of powdered sugar
- Convert ounces to grams: 10.58 × 28.35 = 299.94g
- 1 cup of powdered sugar = 120g
- 299.94g ÷ 120g/cup = 2.50 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar settles significantly during storage. Sifted powdered sugar weighs about 100g per cup compared to 120g unsifted - check whether your recipe means sifted or unsifted.
