How Much Is 1 Teaspoon of Powdered Sugar in Ounces?
Converting 1 teaspoon of powdered sugar to ounces gives 0.09 oz. One teaspoon of powdered sugar weighs 2.5g (0.09 oz). This conversion is specific to powdered sugar because each ingredient has a different density.
Formula and Step-by-Step
- Start with 1 teaspoon of powdered sugar
- 1 teaspoon of powdered sugar = 2.5g
- 1 × 2.5 = 2.5g
- Convert grams to ounces: 2.5 ÷ 28.3495 = 0.09 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar clumps easily. Sift before measuring by volume, or weigh to avoid the sifted-vs-unsifted ambiguity entirely.

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.
