How many grams is two tablespoons of instant yeast?
One teaspoon of instant yeast weighs about 3.13 grams and one tablespoon is about 9.38 grams, so two tablespoons comes out to roughly 18.75 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.)
