450 teaspoons of baking powder equals 76.06 oz. Baking powder has a density of 230g per cup (4.79g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 450 teaspoons of honey would be 112.44 oz.
Formula and Step-by-Step
- Start with 450 teaspoons of baking powder
- 1 teaspoon of baking powder = 4.79g
- 450 × 4.79 = 2,156.25g
- Convert grams to ounces: 2,156.25 ÷ 28.3495 = 76.06 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?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
