About Baking Soda
Baking soda (bicarbonate of soda) is a powerful leavening agent that needs an acid to activate. One US cup weighs approximately 220 grams, the same reference density as baking powder.
Whether you are scaling a recipe up, substituting an ingredient, or converting a recipe from metric to US measurements, having an accurate grams-per-cup value for baking soda removes the guesswork from your cooking. Bookmark this page for quick reference whenever baking soda appears in a recipe.
How much does a cup of baking soda weigh?
A standard US cup of baking soda weighs about 220 grams (7.76 ounces). That makes it about 1.8 times heavier than a cup of all-purpose flour, and heavier than a cup of granulated sugar (200 g). This is why a converter that uses the same factor for every ingredient will give wrong answers: baking soda has its own density, and recipes depend on it.

Values are reference weights for level, unpacked measures unless the ingredient is normally packed. Brand, moisture, temperature and how firmly you fill the cup can shift the result by a few percent, so for precision baking weigh baking soda on a kitchen scale and use the cup figure only as a guide. To understand why these numbers differ between ingredients, read our guide on why a cup of flour is not a cup of sugar, or see why weighing beats measuring cups.
