How Much Is 1 Teaspoon of Baking Powder in Grams?
1 teaspoon of baking powder equals 4.79 g. Baking powder has a density of 230g per cup (4.79g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 1 teaspoon of honey would be 7.08 g.
Formula and Step-by-Step
- Start with 1 teaspoon of baking powder
- 1 teaspoon of baking powder = 4.79g
- 1 × 4.79 = 4.79g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
For 1 teaspoon of baking powder, just remember: 4.79g. Double it for 2 teaspoons (9.58g), halve it for a half teaspoon (2.40g).
Measuring Tip
Baking powder loses potency over time. If yours is more than 6 months old, test it: drop a teaspoon into hot water. If it bubbles vigorously, it is still active.

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.
