Weight of 1 teaspoon baking powder?

The weight of 1 teaspoon of baking powder can vary slightly depending on the density of the powder and how tightly it is packed. However, a general estimate is:

1 teaspoon of baking powder weighs approximately 3-4 grams.

It's important to note that:

* Baking powder is sold by weight, not volume. So, it's always best to use a kitchen scale for accurate measurements.

* The density of baking powder can vary from brand to brand.

If you don't have a scale, you can use a level teaspoon and assume it contains approximately 3.5 grams of baking powder.
