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

tablespoons × 7.5g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 20 tablespoons of powdered sugar
  2. 1 tablespoon of powdered sugar = 7.5g
  3. 20 × 7.5 = 150g
  4. 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.

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.

Frequently Asked Questions

About 5.29 oz, based on powdered sugar having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of tablespoons by 7.5 (grams per tablespoon for powdered sugar), then divide by 28.3495 to convert grams to ounces. For 20 tablespoons: 20 × 7.5 = 150g, then 150 ÷ 28.3495 = 5.29 oz.
For the most accurate results, weigh powdered sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring spoon and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 5.29 oz × 28.3495 = 150g, then 150g ÷ 7.5 = 20 tablespoons. Or use the Ounces to Tablespoons converter.
