Yeast Substitution Converter
Convert a yeast amount between fresh, instant and active dry.
About Yeast Substitution Converter
Yeast types differ in water content and strength, so converting through an instant-yeast baseline gives the right weight. Using the wrong yeast weight under-ferments or over-proofs the dough, so conversion keeps the rise predictable.
Formula
Yeast Substitution
Convert to instant, then to target: fresh = 3x, active dry = 1.33x instant
- instant equivalent
- Amount expressed in terms of instant yeast
Worked example
With the default values below, Yeast Substitution Converter returns Converted Amount of 3.33. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
