Formula and Step-by-Step

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

Start with 0.25 teaspoons of baking soda
1 teaspoon of baking soda = 4.58g
0.25 × 4.58 = 1.15g
Convert grams to ounces: 1.15 ÷ 28.3495 = 0.04 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.
