How Much Is 1.66 Teaspoons of Active Dry Yeast in Grams?
1.66 teaspoons of active dry yeast weighs 4.98 g. This is based on active dry yeast having a density of 144g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.66 teaspoons.
Formula and Step-by-Step
- Start with 1.66 teaspoons of active dry yeast
- 1 teaspoon of active dry yeast = 3g
- 1.66 × 3 = 4.98g
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 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.
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.
