How Much Is 2.89 Ounces of Powdered Sugar in Cups?
2.89 ounces of powdered sugar equals 0.68 cups. That's 81.93g, and Powdered sugar has a density of 120g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 2.89 ounces of powdered sugar
- Convert ounces to grams: 2.89 × 28.35 = 81.93g
- 1 cup of powdered sugar = 120g
- 81.93g ÷ 120g/cup = 0.68 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.

Understanding the Units
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
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.
