Formula and Step-by-Step
- Start with 421 tablespoons of baking powder
- 1 tablespoon of baking powder = 14.38g
- 421 × 14.38 = 6,051.88g
- Convert grams to ounces: 6,051.88 ÷ 28.3495 = 213.47 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.
