Dry Yeast to Fresh Yeast Conversion
A dry yeast to fresh yeast calculator is a valuable tool in baking to convert between different forms of yeast, oz, grams, cups, tablespoons etc.
When a recipe requires 10g of fresh yeast but you only have dry yeast available, you can use the calculator to determine the equivalent amount. Typically, you would need about 1/3 the amount of active dry yeast or 1/4 the amount of instant dry yeast compared to fresh yeast.

Dry Yeast to Fresh Yeast Conversion Formula
The general formula for converting between fresh yeast and dry yeast is:
Fresh yeast to active dry yeast: Multiply the fresh yeast amount by 0.33
Fresh yeast to instant dry yeast: Multiply the fresh yeast amount by 0.25
Dry yeast to fresh yeast: Divide the dry yeast amount by the conversion factor (0.33 for active dry, 0.25 for instant)
Convert 30g of fresh yeast to active dry yeast
Active dry yeast amount = 30g * 0.33 = 9.9g (rounded to 10g for practical use)How Much Dry Yeast is Equivalent to Fresh Yeast?
As a general rule:
1 part active dry yeast = 3 parts fresh yeast
1 part instant dry yeast = 4 parts fresh yeast
If a recipe calls for 20g of fresh yeast, you would use:
- 20g / 3 ≈ 6.7g of active dry yeast, or
- 20g / 4 = 5g of instant dry yeast
7g Dry Yeast to Fresh Yeast
To convert 7g of dry yeast to fresh yeast:
- If it’s active dry yeast: 7g * 3 = 21g fresh yeast
- If it’s instant dry yeast: 7g * 4 = 28g fresh yeast
25g Dry Yeast to Fresh Yeast
To convert 25g of dry yeast to fresh yeast:
- If it’s active dry yeast: 25g * 3 = 75g fresh yeast
- If it’s instant dry yeast: 25g * 4 = 100g fresh yeast
