How Much Is 4.5 Pounds of Powdered Sugar in Cups?
Converting 4.5 pounds of powdered sugar to cups gives 17.01 cups. First convert to grams (4.5 lb = 2,041.17g), then divide by the density of powdered sugar (120g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 4.5 pounds of powdered sugar
- Convert pounds to grams: 4.5 × 453.59 = 2,041.17g
- 1 cup of powdered sugar = 120g
- 2,041.17g ÷ 120g/cup = 17.01 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar dissolves faster than granulated, making it ideal for frostings and glazes. Weight is the most reliable way to measure it consistently.
