How Much Is 138 Grams of Active Dry Yeast in Teaspoons?
138 grams of active dry yeast equals 46.00 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 138 grams of active dry yeast
- 1 cup of active dry yeast = 144g
- 138g ÷ 144g/cup = 0.96 cups × 48 = 46.00 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Active dry yeast can clump or settle during storage. Stir or sift before measuring by volume for consistent results.
