Formula and Step-by-Step

teaspoons × 4.79g/tsp = grams
  1. Start with 2.5 teaspoons of baking powder
  2. 1 teaspoon of baking powder = 4.79g
  3. 2.5 × 4.79 = 11.98g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Baking powder can clump or settle during storage. Stir or sift before measuring by volume for consistent results.

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 a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 11.98 g, based on baking powder having a density of 230g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.79 (grams per teaspoon for baking powder). For 2.5 teaspoons: 2.5 × 4.79 = 11.98 g.
For the most accurate results, weigh baking powder 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.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 11.98 g ÷ 4.79 = 2.5 teaspoons. Or use the Grams to Teaspoons converter.
