One cup, side by side
How much does a teaspoon of baking powder weigh?
4 g — King Arthur's published figure, and the number this page is built on. Baking powder is measured in teaspoons far more often than in cups, so the reference is stated that way; 48 teaspoons to a cup gives the 192 g per cup dishscale uses internally. Convert back and a teaspoon still reads 4 g, because it is the same number either way round.
