Formula and Step-by-Step

teaspoons × 2.5g/tsp = grams
  1. Start with 128 teaspoons of powdered sugar
  2. 1 teaspoon of powdered sugar = 2.5g
  3. 128 × 2.5 = 320g

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 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.

Frequently Asked Questions

About 320.00 g, 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). For 128 teaspoons: 128 × 2.5 = 320.00 g.
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: 320.00 g ÷ 2.5 = 128 teaspoons. Or use the Grams to Teaspoons converter.
