Formula and Step-by-Step

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

Start with 280 teaspoons of baking soda
1 teaspoon of baking soda = 4.58g

Convert grams to ounces: 1,283.33 ÷ 28.3495 = 45.27 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.
