Formula and Step-by-Step

teaspoons × 2.5g/tsp = grams
  1. Start with 150 teaspoons of powdered sugar
  2. 1 teaspoon of powdered sugar = 2.5g
  3. 150 × 2.5 = 375g

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 US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

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 375.00 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 150 teaspoons: 150 × 2.5 = 375.00 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: 375.00 g ÷ 2.5 = 150 teaspoons. Or use the Grams to Teaspoons converter.
