What density is used for baking soda?

This tool uses 220 grams per US cup, which is the standard bulk density for baking soda (sodium bicarbonate) cited by USDA and most culinary references. Sifted or compacted baking soda may vary slightly, so always level off your measuring cup for best accuracy.

How many grams are in 1 teaspoon of baking soda?

One teaspoon of baking soda equals approximately 4.58 grams (220 g ÷ 48 tsp). Most recipes round this to 4.6 g or 5 g for simplicity.

Can I use this for baking powder too?

No. Baking powder has a different density (around 192 g/cup) because it contains cornstarch and acid salts. Use a dedicated baking powder converter for accurate results.

Why does my kitchen scale show a different cup amount?

Actual density varies slightly with humidity, packing, and brand. The 220 g/cup figure is an average. For critical recipes, weigh ingredients directly rather than converting back to volume.

How do I convert cups back to grams?

Multiply the number of cups by 220. For example, 0.5 cup × 220 = 110 grams. You can also enter decimals in this tool to work backwards.
