How Much Is 1.51 Grams of Baking Soda in Teaspoons?
1.51 grams of baking soda equals 0.33 tsp. Baking soda has a density of 220g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 1.51 grams of baking soda
- 1 cup of baking soda = 220g
- 1.51g ÷ 220g/cup = 0.0069 cups × 48 = 0.33 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Baking soda can clump or settle during storage. Stir or sift before measuring by volume for consistent results.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
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.
