How Much Is 7.91 Grams of Active Dry Yeast in Teaspoons?
7.91 grams of active dry yeast equals 2.64 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 7.91 grams of active dry yeast
- 1 cup of active dry yeast = 144g
- 7.91g ÷ 144g/cup = 0.05 cups × 48 = 2.64 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Baking powder loses potency over time. If yours is more than 6 months old, test it: drop a teaspoon into hot water. If it bubbles vigorously, it is still active.

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?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
