How many grams is one tablespoon of active dry yeast?
One teaspoon of active dry yeast weighs about 3.13 grams and one tablespoon is about 9.38 grams, so one tablespoon comes out to roughly 9.38 grams. One standard packet = 7 g = 2¼ tsp = ¼ oz, the same as instant yeast. About 3 g/tsp. Active dry traditionally proofs in warm water first, though King Arthur considers it optional.
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 active dry yeast directly. (For reference, one US cup is 150 g.)
