Quick Answer
One US cup of baking powder weighs about 200 grams. That works out to 12.5 g per tablespoon and 4.17 g per teaspoon. Single-acting, 1 tsp ≈ 4 g. Weights vary slightly by brand, moisture, and how tightly you pack - for precise baking, a kitchen scale beats volume measures.

Frequently Asked Questions
How many grams in 1 cup of baking powder?
About 200 grams, scoop-and-level for dry ingredients. Single-acting, 1 tsp ≈ 4 g.
How many grams in a tablespoon of baking powder?
One US tablespoon (15 mL) of baking powder is about 12.5 grams. A teaspoon is 4.17 g.
Why does baking powder weigh more (or less) than water?
Dry ingredients are weighed by how they pack into the cup volume. Baking Powder has an apparent density of about 0.85 g/mL - lighter than water - depending on particle size and air gaps.
How many cups is 100 g of baking powder?
100 g ÷ 200 g/cup ≈ 0.50 cups - about a little less than a full cup. The reverse table on this page covers 25-1000 g.
Should I weigh or measure by volume?
Weighing is more accurate - volume measures vary with how you scoop, pack, and level, and brands differ by 5-15%. For cookies and cakes where ratios matter, grams are the professional standard. The tables here convert either direction.
