How Much Is 0.42 Ounces of Baking Soda in Tablespoons?
Converting 0.42 ounces of baking soda to tablespoons gives 0.87 tbsp. First convert to grams (0.42 oz = 11.91g), then divide by the density of baking soda (220g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 0.42 ounces of baking soda
- Convert ounces to grams: 0.42 × 28.35 = 11.91g
- 1 cup of baking soda = 220g
- 11.91g ÷ 220g/cup = 0.05 cups × 16 = 0.87 tablespoons
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.
