Convert baking soda grams ⇄ teaspoons

A level teaspoon of baking soda (bicarbonate of soda) weighs about 4.8 g.
Presets
2.0833 tsp
10 g = 2.0833 tsp (at 4.8 g per US teaspoon)

Formula: 10 g ÷ 4.8 g/tsp = 2.0833 tsp

Approximate weights: baking soda weights per teaspoon vary with brand and how level the spoon is — 4.8 g is a typical level-teaspoon value. Baking soda is potent: too much leaves a soapy, metallic taste, so weigh it when precision matters.

How the baking soda conversion works

The converter applies teaspoons = grams ÷ grams-per-teaspoon. A level US teaspoon of baking soda weighs about 4.8 g — heavier per spoon than baking powder's 4 g, because the soda is denser, and the difference matters: baking soda needs an acid in the recipe to activate, and too much of it leaves a soapy, metallic taste that no amount of sugar hides.

Worked example: a recipe calling for 9.6 g of baking soda needs 9.6 ÷ 4.8 = 2 teaspoons. A recipe calling for 10 g needs 10 ÷ 4.8 = 2.1 teaspoons — round to 2 for most bakes.

Quick reference

  • ½ tsp baking soda — 2.4 g

baking soda questions

How many grams is a teaspoon of baking soda?
About 4.8 g for a level US teaspoon. A heaped teaspoon can hold more, which is why recipes that need precision give weights — with baking soda, a gram either way can change the taste.
How many teaspoons is 10 g of baking soda?
About 2.1 teaspoons (10 ÷ 4.8). Round to 2 teaspoons for most recipes — and remember that baking soda is stronger than baking powder, so never swap them one-for-one.
How many grams is a tablespoon of baking soda?
About 14.4 g — one tablespoon is 3 teaspoons, and 3 × 4.8 g = 14.4 g. Most recipes need far less than a tablespoon; if yours calls for one, double-check it against the acid in the recipe.
Is baking soda the same as bicarbonate of soda?
Yes — baking soda is the US name for bicarbonate of soda (sodium bicarbonate). The weights are identical; only the label differs. It is not the same as baking powder, which already contains its own acid.
Can I convert teaspoons of baking soda back to grams?
Yes — switch the direction above. Grams = teaspoons × grams-per-teaspoon, so 2 teaspoons of baking soda is 2 × 4.8 = 9.6 g.
