Grams to Cups: Baking Soda
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for baking soda. One cup of baking soda weighs about 230 grams, which works out to a density of 0.97 g/ml. From there, half a cup is roughly 115 g, a quarter cup about 58 g, and one tablespoon about 14 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of baking soda does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of baking soda rather than a one-size-fits-all figure.

How to measure baking soda accurately
For baking soda, spoon it into the cup and level it off; do not shake or tap the cup, which settles the contents and changes the weight. Weighing in grams is still the most reliable method when the amount matters.
