Baking soda, also known as sodium bicarbonate, is a versatile leavening agent used in baking. When combined with acidic ingredients like yoghurt, lemon juice, or vinegar, it produces carbon dioxide gas, which helps dough and batter rise. Baking soda is commonly used in recipes for cookies, cakes, and quick breads.

Baking soda is roughly three times stronger than baking powder, so even a small over-measure can leave a soapy, metallic taste. Measuring by weight rather than volume gives you more consistent results. Use the converter below for grams, cups, teaspoons, and more.

Baking powder is baking soda already blended with a dry acid and a starch, so it is milder and acts on its own without extra acidic ingredients. To swap baking soda for baking powder, use roughly three times as much and drop any added acid from the recipe. See our Baking Powder converter.

Cream of tartar is the acid that pairs with baking soda to replace baking powder. Use the cream of tartar converter for teaspoon and gram conversions. See our Cream of Tartar converter.
