About measuring baking powder
Baking powder is a blend of baking soda, an acid and a little starch, so it is slightly lighter than pure baking soda. A full cup weighs about 192 grams, but as with soda you almost always work in teaspoons, where one teaspoon is close to 4 grams. Because it loses potency over time, both the amount and the freshness matter. If your bakes have stopped rising well, old baking powder measured by an inaccurate spoon is a common culprit.
Baking powder weakens with age. Measure it accurately and replace it every six to twelve months.
Frequently asked questions

One US cup of baking powder is about 192 grams. It is a little lighter than baking soda because it contains starch and acid as well.
How many grams is a teaspoon of baking powder?
About 4 grams. A teaspoon is the usual working measure, since recipes rarely need more than a spoonful or two.
Can I substitute baking soda for baking powder?
Not directly. Baking soda is far stronger and needs an added acid. Swapping them by weight will throw off both the rise and the taste.
