How Much Is 45 Grams of Active Dry Yeast in Teaspoons?
45 grams of active dry yeast equals 15.00 tsp. Active dry yeast has a density of 144g per cup. Because grams measure weight and teaspoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 45 grams of active dry yeast
- 1 cup of active dry yeast = 144g
- 45g ÷ 144g/cup = 0.31 cups × 48 = 15.00 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.

Understanding the Units
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
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.
