How Much Is 3 Teaspoons of Powdered Sugar in Ounces?
3 teaspoons of powdered sugar equals 0.26 oz. Powdered sugar has a density of 120g per cup (2.5g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 3 teaspoons of honey would be 0.75 oz.
Formula and Step-by-Step
- Start with 3 teaspoons of powdered sugar
- 1 teaspoon of powdered sugar = 2.5g
- 3 × 2.5 = 7.5g
- Convert grams to ounces: 7.5 ÷ 28.3495 = 0.26 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar settles significantly during storage. Sifted powdered sugar weighs about 100g per cup compared to 120g unsifted - check whether your recipe means sifted or unsifted.

Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
