Single-conversion pages for baking soda
Working with baking soda
Baking Soda sits in the leaveners, salt & spices group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. 1 teaspoon = 4.6 g. Baking soda is roughly 3–4 times stronger than baking powder, so never swap 1:1.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
Also sold as: bicarbonate of soda. These names refer to the same product and use the same weight per cup.
Frequently asked questions
How many grams are in a cup of baking soda?
One US cup of baking soda weighs about 220 grams (7.76 oz). 1 teaspoon = 4.6 g. Baking soda is roughly 3–4 times stronger than baking powder, so never swap 1:1.
How many grams are in a tablespoon of baking soda?
One US tablespoon holds about 13.8 g, and one teaspoon about 4.58 g, since a tablespoon is 14.79 ml and a teaspoon 4.93 ml.
How many cups is 100 g of baking soda?
100 grams of baking soda is roughly 0.455 US cups. Weighing is more reliable than filling a cup, especially for leaveners, salt & spices.
Where does this figure come from?
The density used here is 0.930 g/ml, based on NIST Handbook 133. Treat it as an approximation: real batches vary with brand, moisture and how the cup is filled.
