How Much Is 18 Teaspoons of Powdered Sugar in Grams?
18 teaspoons of powdered sugar weighs 45.00 g. This is based on powdered sugar having a density of 120g per cup. Because teaspoons 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 teaspoons.
Formula and Step-by-Step
- Start with 18 teaspoons of powdered sugar
- 1 teaspoon of powdered sugar = 2.5g
- 18 × 2.5 = 45g
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 teaspoons measurements. Your amount (18 teaspoons) is highlighted.
For reference, 18 teaspoons of powdered sugar (45g) is close in weight to a golf ball (46g).

Understanding the Units
What is a Teaspoon?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
