How Much Is 18.9 Cups of Powdered Sugar in Grams?
18.9 cups of powdered sugar weighs 2,268.00 g. This is based on powdered sugar having a density of 120g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 18.9 cups.
Formula and Step-by-Step
- Start with 18.9 cups of powdered sugar
- 1 cup of powdered sugar = 120g

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.
