How Much Is 0.9 Cups of Powdered Sugar in Ounces?
0.9 cups of powdered sugar equals 3.81 oz. Powdered sugar has a density of 120g per cup (120g per cup), which means it's relatively light compared to other common cooking ingredients. For comparison, 0.9 cups of honey would be 10.79 oz.
Formula and Step-by-Step
- Start with 0.9 cups of powdered sugar
- 1 cup of powdered sugar = 120g
- 0.9 × 120 = 108g
- Convert grams to ounces: 108 ÷ 28.3495 = 3.81 oz
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.
Powdered Sugar at Different Amounts
How powdered sugar scales across common cups measurements. Your amount (0.9 cups) is highlighted.
For reference, 0.9 cups of powdered sugar (108g) is close in weight to a bar of soap (113g).

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
