Bake with Confidence: The Professional Yeast Converter
The difference between a perfect rise and a flat loaf often comes down to using the right type of yeast. Because Instant, Active Dry, and Fresh Baker’s Yeast all have different potencies and densities, you cannot swap them one-for-one. This Free Yeast Conversion Calculator does the math for you, ensuring your bread, pizza dough, and pastries turn out perfectly every time.
This tool is completely free, requires no sign-up, and offers unlimited use for home bakers and professional pastry chefs.
Understanding Yeast Ratios
Yeast types vary significantly in their moisture content and concentration of live cells. This tool uses the industry-standard conversion ratios to maintain the structural integrity of your dough:
- Instant Yeast to Active Dry: Instant yeast is about 25% more potent by weight than active dry.
- Fresh Yeast to Dry Yeast: Fresh yeast (compressed) contains much more water; you generally need 3x the weight of fresh yeast to equal the potency of dry yeast.
- Volume vs. Weight: Unlike water, yeast has different densities. 1 teaspoon of Instant yeast weighs less than 1 teaspoon of Fresh yeast. This tool automatically adjusts for these "Grams per Teaspoon" differences.
Key Features:
- 4 Major Yeast Types: Convert between Instant (Rapid Rise), Active Dry, Fresh (Cake), and Brewers’ Yeast.
- Volume & Mass Support: Seamlessly switch between kitchen measurements (teaspoons, tablespoons, cups) and precision baking weights (grams, ounces, pounds).
- Smart Rounding Logic: Results are cleaned for easy reading (e.g., "2.25" instead of "2.250"), providing the precision needed for baking without the clutter of extra zeros.
- Bi-Directional Calculation: Set your "From" and "To" units independently to match any recipe from any country.
