Enter a yeast amount to see all three equivalents.

Uses the general fresh-to-active-dry factor 0.4 and fresh-to-instant factor 0.33 from King Arthur Baking; reverse conversions use the same ratios. Manufacturers differ, so a product's own instructions take precedence, especially for bread machines. Dry teaspoon and packet equivalents use Red Star's approximate 7 g = 2¼ tsp = one standard packet. This converts quantity only, not rising time, liquid, viability or dough handling. Nothing is saved or sent anywhere.
