How Much Is 1 Teaspoon of Active Dry Yeast in Ounces?
Converting 1 teaspoon of active dry yeast to ounces gives 0.11 oz. One teaspoon of active dry yeast weighs 3g (0.11 oz). This conversion is specific to active dry yeast because each ingredient has a different density.
Formula and Step-by-Step
- Start with 1 teaspoon of active dry yeast
- 1 teaspoon of active dry yeast = 3g
- 1 × 3 = 3g
- Convert grams to ounces: 3 ÷ 28.3495 = 0.11 oz
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?
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.
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
