How Much Is 1 Gram of Active Dry Yeast in Teaspoons?
1 gram of active dry yeast equals 0.33 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 1 gram of active dry yeast
- 1 cup of active dry yeast = 144g
- 1g ÷ 144g/cup = 0.0069 cups × 48 = 0.33 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?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
