How it works
Baking soda is about three times as strong as baking powder, so one teaspoon of soda stands in for about three teaspoons of powder. Going the other way, divide by three.
A swap is an estimate. Baking powder also contains acid, so a straight swap can change the taste and the rise of a bake.
Worked example
To swap 1 tsp of one for the other, use 0.33 tsp.
Questions
Can I swap them one for one?
No. Baking soda is far stronger, so a one for one swap can leave a bitter taste. Use the converted amount from this page.
Does this work in every recipe?
Not always. Recipes that rely on a lot of leavening, or that have no acid, may behave differently from the one you planned.
What is the difference between them?
Baking powder is baking soda with an acid already mixed in, usually with a starch to keep it dry.
