How Much Is 2.5 Grams of Powdered Sugar in Cups?
2.5 grams of powdered sugar equals 0.02 cups. Powdered sugar has a density of 120g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 2.5 grams of powdered sugar
- 1 cup of powdered sugar = 120g
- 2.5g ÷ 120g/cup = 0.02 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.
