How Much Is 420 Teaspoons of Baking Soda in Grams?
420 teaspoons of baking soda weighs 1,925.00 g. This is based on baking soda having a density of 220g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 420 teaspoons.
Formula and Step-by-Step
- Start with 420 teaspoons of baking soda
- 1 teaspoon of baking soda = 4.58g
- 420 × 4.58 = 1,925g
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.

Understanding the Units
What is a Teaspoon?
A teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.
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.
