Baking powder: measure by the teaspoon
Baking powder is used in small amounts, so the teaspoon matters more than the cup — a teaspoon weighs about 4.6 g. A typical rule of thumb is 1 to 1¼ teaspoons per cup of flour for a standard rise. Most supermarket baking powder is double-acting, releasing gas both when mixed and again in the oven.
It loses strength over time; to test, stir a teaspoon into hot water and look for an immediate fizz.

Where baking powder sits by weight
A cup of baking powder weighs 221 g, which puts it 7th by weight among the 9 spices & leaveners on this site. Its nearest neighbours are vanilla extract at 208 g and baking soda at 230 g per cup.
Swapping these by the cupful is not like-for-like. A cup of baking soda in place of baking powder puts roughly 9 g more in the bowl, so match the grams rather than the cups.
