Grams to Tablespoons – Baking Soda
Typical density ≈0.99 g/mL → 1 tbsp ≈14.6 g.
Baking Soda Calculator
Formula: tablespoons = grams ÷ 14.6 (approx.).
What Are Grams and Tablespoons?
A gram (g) is a unit of mass in the metric system (1 g ≈0.03527 oz). A tablespoon (tbsp) is a unit of volume equal to 3 teaspoons, or about 14.7868 milliliters. Mass and volume measure different things, so you need the ingredient's density to convert between them.1
Baking Soda Density and Formula
Baking soda (sodium bicarbonate) has a density of approximately 0.99 g/mL, which is very close to water's density. This density gives us approximately 14.6 grams per tablespoon. Baking soda is a key leavening agent that requires an acid to activate.
tablespoons = grams ÷ 14.6
grams = tablespoons Ã 14.6
More precisely, tablespoons = grams ÷ (14.7868 Ã density). For baking soda with density ~0.99 g/mL, this gives approximately 14.6 grams per tablespoon.2
Note: Results are approximate. How baking soda is packed into the measuring spoon can affect the volume. Baking soda has an indefinite shelf life if stored properly in a cool, dry place.

Assumes 1 tbsp ≈14.6 g for baking soda. Real-world results vary based on how it packs into the measuring spoon.
Tips for Accurate Measuring
- Weighing is most reliable: A kitchen scale provides the most accurate baking soda measurements.2
- Spoon and level: Gently spoon baking soda into a tablespoon and level the top with a straight edge. Don't pack it down.
- Storage: Keep baking soda in a cool, dry place in an airtight container. It has an indefinite shelf life if stored properly.
- Don't confuse with baking powder: Baking soda and baking powder have similar densities but serve different purposes. Baking soda needs an acid to activate, while baking powder contains its own acid.
- Test freshness: To test if baking soda is still active, mix 1/4 teaspoon with 2 teaspoons vinegarâ€â€Âit should bubble immediately.
FAQs
How many tablespoons is 50 g of baking soda?
About 3.42 tbsp (50 ÷ 14.6). Use the calculator for exact rounding.
How many grams is 3 tablespoons of baking soda?
About 43.8 g (3 Ã 14.6).
What's the difference between baking soda and baking powder?
Baking soda is pure sodium bicarbonate and requires an acid to activate, while baking powder contains both an acid and a base. Both have similar densities (~0.99 g/mL) but serve different purposes in recipes.
Does baking soda expire?
Baking soda has an indefinite shelf life if stored in a cool, dry place. However, if it's been exposed to moisture or strong odors, it may lose effectiveness and should be replaced.
Can I substitute baking soda for baking powder?
No, they're not interchangeable. Baking soda needs an acid to activate, while baking powder contains its own acid. Substituting requires recipe adjustments.
