How Much Is 1.5 Teaspoons of Powdered Sugar in Ounces?

1.5 teaspoons of powdered sugar weighs 0.13 oz. This is based on powdered sugar having a density of 120g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.5 teaspoons.

Formula and Step-by-Step

teaspoons × 2.5g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 1.5 teaspoons of powdered sugar
  2. 1 teaspoon of powdered sugar = 2.5g
  3. 1.5 × 2.5 = 3.75g
  4. Convert grams to ounces: 3.75 ÷ 28.3495 = 0.13 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?

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 an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 0.13 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 1.5 teaspoons: 1.5 × 2.5 = 3.75g, then 3.75 ÷ 28.3495 = 0.13 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.
