How Much Is 28 Tablespoons of Baking Soda in Ounces?
28 tablespoons of baking soda weighs 13.58 oz. This is based on baking soda having a density of 220g per cup. Because tablespoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 28 tablespoons.
Formula and Step-by-Step
- Start with 28 tablespoons of baking soda
- 1 tablespoon of baking soda = 13.75g
- 28 × 13.75 = 385g
- Convert grams to ounces: 385 ÷ 28.3495 = 13.58 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?
One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.
