How Much Is 25 Teaspoons of Baking Powder in Ounces?
25 teaspoons of baking powder weighs 4.23 oz. This is based on baking powder having a density of 230g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 25 teaspoons.
Formula and Step-by-Step
- Start with 25 teaspoons of baking powder
- 1 teaspoon of baking powder = 4.79g
- 25 × 4.79 = 119.79g
- Convert grams to ounces: 119.79 ÷ 28.3495 = 4.23 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?
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 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.
