Formula and Step-by-Step

tablespoons × 13.75g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 656 tablespoons of baking soda
  2. 1 tablespoon of baking soda = 13.75g
  3. 656 × 13.75 = 9,020g
  4. Convert grams to ounces: 9,020 ÷ 28.3495 = 318.17 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.

Understanding the Units

What is a Tablespoon?

A tablespoon is roughly the volume of a large soup spoon. In precise terms, 1 US tablespoon equals 14.787 ml, which is very close to the 15 ml metric standard used in most of the world. Three teaspoons make one tablespoon.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 318.17 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 656 tablespoons: 656 × 13.75 = 9,020g, then 9,020 ÷ 28.3495 = 318.17 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: 318.17 oz × 28.3495 = 9,020g, then 9,020g ÷ 13.75 = 656 tablespoons. Or use the Ounces to Tablespoons converter.
