Formula and Step-by-Step

teaspoons × 4.58g/tsp ÷ 28.3495g/oz = ounces

Start with 90 teaspoons of baking soda
1 teaspoon of baking soda = 4.58g
90 × 4.58 = 412.5g
Convert grams to ounces: 412.5 ÷ 28.3495 = 14.55 oz

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

Measuring Tip

Leavener measurements are critical because even small differences affect rise and texture. When possible, weigh baking soda rather than relying on volume.

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.
