Why do I need to convert yeast types?
Different yeast types have different moisture and activity levels, so using the same weight can affect dough rise. Conversion ensures consistent results.
Can I use this for sourdough starter?
No, this calculator is for commercial yeast types only. Sourdough starter has different properties and requires separate conversion.
What if my recipe calls for a different amount?
Simply enter the amount you have and the calculator will give you the equivalent for the target type. Adjust other ingredients as needed.

Formules
Les mathématiques derrière cette calculatrice, écrites pour que vous puissiez vérifier le résultat.
Active Dry to Instant
Instant yeast is more concentrated, so you need less of it.
Example:
Input: Active Dry = 10 g
Calculation: 10 × 0.75
Result: 7.5 g instant yeast
Active Dry to Fresh
Fresh yeast has high moisture content, so you need more of it.
Example:
Input: Active Dry = 10 g
Calculation: 10 × 3
Result: 30 g fresh yeast
Cas d'utilisation réels
Où ce calcul apparaît dans la vie quotidienne.
Substituting yeast in a recipe
When you only have one type of yeast but the recipe calls for another, use this conversion to keep the dough rise consistent.
Example: Recipe calls for 7 g instant yeast, you have active dry: use 9.3 g active dry.
Scaling recipes
When adjusting recipe quantities, convert the yeast amount to match the new batch size.
Example: Doubling a recipe that uses 5 g fresh yeast: convert to instant if needed.
Baking with what you have
Avoid a trip to the store by converting the yeast you have on hand to the amount needed.
Example: You have fresh yeast but recipe calls for active dry.
Conseils et erreurs courantes
Tips
- Always use weight measurements for accuracy, not volume.
- Store yeast properly to maintain its activity.
- When substituting, adjust liquid in the recipe if needed, as fresh yeast adds moisture.
- Proof active dry yeast in warm water before using, but instant yeast can be mixed directly with flour.
Common Mistakes to Avoid
- Using the same weight for different yeast types without conversion.
- Forgetting that fresh yeast has a short shelf life.
- Not adjusting liquid when using fresh yeast instead of dry.
Hypothèses et limites
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
