Formula and Step-by-Step

tablespoons × 13.75g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 145 tablespoons of baking soda
  2. 1 tablespoon of baking soda = 13.75g
  3. 145 × 13.75 = 1,993.75g
  4. Convert grams to ounces: 1,993.75 ÷ 28.3495 = 70.33 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.

Frequently Asked Questions

About 70.33 oz, based on baking soda having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of tablespoons by 13.75 (grams per tablespoon for baking soda), then divide by 28.3495 to convert grams to ounces. For 145 tablespoons: 145 × 13.75 = 1,993.75g, then 1,993.75 ÷ 28.3495 = 70.33 oz.
For the most accurate results, weigh baking soda on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 70.33 oz × 28.3495 = 1,993.75g, then 1,993.75g ÷ 13.75 = 145 tablespoons. Or use the Ounces to Tablespoons converter.
