How Much Is 1.5 Teaspoons of Baking Powder in Ounces?
Converting 1.5 teaspoons of baking powder to ounces gives 0.25 oz. One teaspoon of baking powder weighs 4.79g, so 1.5 teaspoons is 1.5 × 4.79 = 7.19g (0.25 oz). This conversion is specific to baking powder because each ingredient has a different density.
Formula and Step-by-Step
- Start with 1.5 teaspoons of baking powder
- 1 teaspoon of baking powder = 4.79g
- 1.5 × 4.79 = 7.19g
- Convert grams to ounces: 7.19 ÷ 28.3495 = 0.25 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?
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.
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.
