Yeast Converter

About the Yeast Converter

Converts a yeast quantity between fresh (cake) yeast, active dry yeast and instant (rapid-rise) yeast using standard baking ratios.

How to use

Enter an amount, its yeast type and the target type, then click Convert.

Worked example

10 g fresh yeast ≈ 5 g active dry ≈ 3.3 g instant.

How to use this calculator

1. Enter the yeast amount you have.
2. Choose the yeast type you are converting from.
3. Choose the yeast type you want to convert to.
4. Read the converted amount and round as needed for your recipe.

The formula explained

• \(\text{fresh}\) = fresh yeast amount
• \(\text{active dry}\) = active dry yeast amount
• \(\text{instant}\) = instant yeast amount

Step by step method

1. Start with the amount of yeast from your recipe or package.
2. Identify whether it is fresh, active dry, or instant yeast.
3. Use the converter to switch to the target yeast type.
4. If your recipe needs precision, measure carefully and round to a practical baking amount.

Worked example

Suppose a recipe calls for 30 grams of fresh yeast, and you want to use active dry yeast instead.

1. Use the fresh to active dry relationship, which is \(\text{active dry} = \frac{\text{fresh}}{3}\).
2. Substitute 30 grams for fresh: \(30 \div 3 = 10\).
3. So the converted amount is 10 grams of active dry yeast.

Tips and common mistakes

• Check whether your recipe expects fresh, active dry, or instant yeast before converting.
• Measure carefully, especially for small quantities, because small differences can affect rising.
• If a recipe includes proofing or blooming instructions, active dry and instant yeast may not be handled the same way.
• Use the converted amount as a baking guide, then adjust slightly only if your recipe specifically recommends it.
