How many grams is half a tablespoon of baking powder?
½ tablespoon of baking powder ≈ 6 g
One teaspoon of baking powder weighs about 4 grams and one tablespoon is about 12 grams, so half a tablespoon comes out to roughly 6 grams. Baking powder is measured by the teaspoon — one level teaspoon is about 4 grams.
Small spoon amounts are where weighing has the biggest payoff: tiny errors compound in baking. If your scale reads in 1-gram steps you can measure baking powder directly. (For reference, one US cup is 192 g.)
