What this tool does
Fresh yeast is mostly water, so dry yeasts are more concentrated: the usual rule of thumb is that active dry yeast is about 40 % of the weight of fresh and instant yeast about a third. Treat it as a starting point, because brands differ and the pack of the yeast you buy is the better guide. Instant yeast can usually be mixed straight into the flour, while active dry yeast is often dissolved in warm liquid first; a little more time to rise is normal when you use less yeast.
Formula
fresh : active dry : instant ≈ 1 : 0.4 : 0.33 (rule of thumb)
