How Much Is 20 Tablespoons of Powdered Sugar in Ounces?
20 tablespoons of powdered sugar weighs 5.29 oz. This is based on powdered sugar having a density of 120g per cup. Because tablespoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 20 tablespoons.
Formula and Step-by-Step
- Start with 20 tablespoons of powdered sugar
- 1 tablespoon of powdered sugar = 7.5g
- 20 × 7.5 = 150g
- Convert grams to ounces: 150 ÷ 28.3495 = 5.29 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.
Powdered Sugar at Different Amounts
How powdered sugar scales across common tablespoons measurements. Your amount (20 tablespoons) is highlighted.
For reference, 20 tablespoons of powdered sugar (150g) is close in weight to a baseball (145g).

Understanding the Units
What is a Tablespoon?
Tablespoon sizes differ by country. A US tablespoon is 14.787 ml, close to the 15 ml metric standard used in most countries. An Australian tablespoon is 20 ml, about 35% larger than US. An imperial tablespoon is 17.758 ml. If your recipe comes from Australia, the larger tablespoon size can make a real difference.
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.
