Formula and Step-by-Step

teaspoons × 2.5g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 120 teaspoons of powdered sugar
  2. 1 teaspoon of powdered sugar = 2.5g
  3. 120 × 2.5 = 300g
  4. Convert grams to ounces: 300 ÷ 28.3495 = 10.58 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 teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.

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 10.58 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 teaspoons by 2.5 (grams per teaspoon for powdered sugar), then divide by 28.3495 to convert grams to ounces. For 120 teaspoons: 120 × 2.5 = 300g, then 300 ÷ 28.3495 = 10.58 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.
