Yeast Converter
The three commercial yeasts are interchangeable by a simple ratio: instant is the most concentrated, active dry needs about a quarter more, and fresh cake yeast needs roughly three times the weight of instant. Sourdough starter is different again, since only a small fraction of it is yeast.
