About the Yeast Substitution Calculator
What is the Yeast Substitution Calculator?
Recipes call for different yeast types. This yeast substitution calculator converts the amount so your dough rises the same.
It works in grams or teaspoons.
How to use the Yeast Substitution Calculator
- Amount in the Recipe (sample: 7)
- Unit (sample: Grams)
- Recipe Uses (sample: Instant yeast)
- You Have (sample: Active dry yeast)
- Press Convert Yeast (results also refresh as you type). The result card shows the Amount to Use, along with In teaspoons (approx.), Recipe amount in grams, How to use and Rise time.
Formula used
1 g instant = 1.25 g active dry = 3 g fresh yeast
- 1 tsp = about 3.1 g dry yeast
- 1 packet = 7 g (2¼ tsp)
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:

Tips for using the Yeast Substitution Calculator
- Water above 50 °C kills yeast – lukewarm is best.
- Test old yeast in warm water with sugar; if it does not foam in 10 minutes, replace it.
