Notes
Many yeast brands say instant and active dry can be swapped 1:1; the 1.25 factor compensates for active dry yeast's slightly lower activity.
Fresh to instant: divide by 3 (some bakers use 2.5).
Weighing is more accurate than teaspoons, especially for small amounts.
For any other amount, use the yeast conversion calculator .
