Formula and Step-by-Step

teaspoons × 4.79g/tsp ÷ 28.3495g/oz = ounces

Start with 0.9 teaspoons of baking powder
1 teaspoon of baking powder = 4.79g
0.9 × 4.79 = 4.31g
Convert grams to ounces: 4.31 ÷ 28.3495 = 0.15 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Baking powder can clump or settle during storage. Stir or sift before measuring by volume for consistent results.

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?

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.
