Baking soda (bicarb) is the pure alkali inside baking powder, with no built-in acid, so it is roughly three times stronger. They are not a 1:1 swap: to replace baking powder with baking soda you need to add an acid such as cream of tartar, and use about a third of the amount. See what 1 ounce of baking soda (bicarb) is in cups.
Cream of tartar is the dry acid inside baking powder. Use the cream of tartar converter for teaspoon and gram conversions when pairing it with baking soda. See our Cream of Tartar converter.
