How Much Is 21.08 Grams of Active Dry Yeast in Teaspoons?
21.08 grams of active dry yeast equals 7.03 tsp. Active dry yeast has a density of 144g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 21.08 grams of active dry yeast
- 1 cup of active dry yeast = 144g
- 21.08g ÷ 144g/cup = 0.15 cups × 48 = 7.03 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Leavener measurements are critical because even small differences affect rise and texture. When possible, weigh active dry yeast rather than relying on volume.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Teaspoon?
One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.
