About Yeast Converter
Recipes call for whichever yeast the author had on hand; the standard substitution table says 1 teaspoon of instant equals about 1¼ teaspoons of active dry or ⅓ ounce of fresh yeast. Enter what you have — in grams or teaspoons — and see all three equivalents side by side.
Common uses
- Substitute instant yeast in a recipe written for fresh cake yeast
- Convert a 7 g packet into teaspoons for a small batch
- Scale yeast down for an overnight dough without a scale-friendly recipe
Example
Input
7 g active dry yeast
Output
5.6 g instant (1.78 tsp) · 16.8 g fresh (0.59 oz)
Limitations
- Conversion uses the common home-baking table; yeast brands vary a little in potency and density.
- Active dry likes proofing in warm water first; instant can be mixed straight into flour.
Frequently asked questions
How do I substitute active dry yeast for instant yeast?
Use 25% more by weight or volume — 1 teaspoon of instant equals about 1.25 teaspoons of active dry. Going the other way, multiply the active dry amount by 0.8 to get the instant equivalent.
How much fresh yeast equals a packet of dry yeast?
A 7 g packet of instant yeast equals about 21 g of fresh cake yeast — fresh is roughly three times the weight of instant because most of it is moisture. From active dry, multiply by 2.4 instead.
Why can't I swap yeast types gram for gram?
The three forms pack different amounts of live yeast per gram: fresh yeast is mostly water, and active dry granules carry a coating of inactive cells that instant yeast largely lacks. The standard table — 1 : 1.25 : 3 for instant, active dry, and fresh — corrects for that.
How many teaspoons are in a 7 g yeast packet?
About 2¼ teaspoons, using roughly 3.15 g per teaspoon — a figure that holds for both instant and active dry yeast. Fresh yeast is sold by weight (a third of an ounce of fresh replaces a teaspoon of instant), not by the spoon.
