Why baking soda needs its own conversion
Baking Soda weighs about 288g per cup — notably dense — closer to syrups than most dry ingredients. REALISTIC UNIT: 1/2 teaspoon = 3 g, so 1 tsp = 6 g (King Arthur). Cup value is extrapolated and impractical. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — baking soda does not weigh the same per cup as most other ingredients.
- Measurement note: REALISTIC UNIT: 1/2 teaspoon = 3 g, so 1 tsp = 6 g (King Arthur). Cup value is extrapolated and impractical.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.

Does this conversion work for every brand or variety of baking soda?
It’s a close approximation based on King Arthur Baking. Minor variations in moisture, grain, or brand can shift the exact weight slightly, but this figure works well for everyday cooking and baking.
