How many grams is one tablespoon of instant yeast?
One teaspoon of instant yeast weighs about 3.13 grams and one tablespoon is about 9.38 grams, so one tablespoon comes out to roughly 9.38 grams. Instant yeast is measured by the teaspoon — one teaspoon is about 3 grams, and a standard packet is 7 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 instant yeast directly. (For reference, one US cup is 150 g.)
