Yeast conversion chart
Instant and active dry share the spoon weight. Fresh yeast is the professional factor run backwards: instant ÷ 0.33, or active dry ÷ 0.40. A packet is 7 g.
| Measure | Instant or active dry | Fresh, from instant | Fresh, from active dry |
|---|---|---|---|
| 1 level teaspoon | 3 g | 9.1 g | 7.5 g |
| 2 level teaspoons | 6 g | 18.2 g | 15 g |
| 1 packet (7 g) | 7 g | 21 g | 17.5 g |

Quick answer. One level teaspoon of instant or active dry yeast is 3 g. That is 9.1 g fresh if you started from instant, and 7.5 g fresh if you started from active dry.

Questions
- Why is a level teaspoon 3 g?
- King Arthur’s ingredient weight chart lists 2 teaspoons of instant yeast as 6 g. This chart divides that by two. The same chart lists 2¼ teaspoons as 7 g, so a 7 g packet is not written as 7 ÷ 3 teaspoons.
- Why are there two fresh-yeast columns?
- King Arthur’s professional reference uses fresh × 0.33 for instant and fresh × 0.40 for active dry. Reversing those factors gives two different fresh weights for the same dry weight. Both are printed.
- Why is fresh yeast not shown in teaspoons?
- The sources used here give fresh yeast by weight. They do not give a gram weight for a teaspoon of fresh yeast, so this chart does not invent one.
- Will this print on one page?
- The printed page is the chart, the one-line source, and the luuzo.com address. Questions, the site header, and the site footer are left off. It is sized for A4 or Letter.

Spoon weights follow King Arthur’s chart (2 tsp = 6 g). Fresh weights use the professional 0.33 and 0.40 factors.
