How Much Is 155 Teaspoons of Baking Soda in Ounces?
155 teaspoons of baking soda equals 25.06 oz. Baking soda has a density of 220g per cup (4.58g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 155 teaspoons of honey would be 38.73 oz.
Formula and Step-by-Step
- Start with 155 teaspoons of baking soda
- 1 teaspoon of baking soda = 4.58g
- 155 × 4.58 = 710.42g
- Convert grams to ounces: 710.42 ÷ 28.3495 = 25.06 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 Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
