Baking Soda ingredient guide →1 pound of Baking Soda in cups
Also known as bicarbonate of soda, bicarb soda, bicarb.
1 pound of baking soda = 2.1 US cups. That's based on a 216 g per cup baseline. Baking Soda is also called bicarbonate of soda in some recipes. Because baking soda can shift with brand and measuring style, weighing is usually more accurate than measuring by volume.

What the sources say baking soda weighs
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| USDA FoodData Central | 1 tsp | 4.6 g |
| King Arthur Baking | 1/2 tsp | 3 g |
CupOrGram standardizes on 216 g per cup (14 g per tablespoon, 5 g per teaspoon) and uses that single value on every page — how we reconcile the sources.
Why this conversion varies
Baking Soda can vary by brand and measuring style.
- Baking Soda may settle, compress, or pour differently based on handling.
- baking soda can shift with temperature and ingredient texture.
- This page uses a consistent 216 g per cup baseline for repeatable conversions.
Why this conversion matters
Baking Soda can behave differently by brand and handling. Converting baking soda with a consistent baseline gives you a more dependable starting point for scaling recipes.
Practical baking use
Pure sodium bicarbonate. Requires an acid in the recipe to activate. Use this conversion as a practical starting point for scaling recipes with baking soda.
- If consistency matters, verify with a small test batch first.
- Use weight-based measurements when precision is critical.
FAQ
How much is 1 pound of baking soda in US cups?

Why can baking soda conversion values vary in home kitchens?
Baking Soda can vary by brand and measuring style. In practice, brand and measuring style can shift results between kitchens.
Is it better to weigh baking soda for baking?
Usually yes. Weight-based measuring reduces shifts from brand and measuring style, so your results are more repeatable.

Recipe Context for Baking Soda
For chemical leavening: small weight changes alter rise and browning.
For quick breads: over-leavening can cause collapse after oven spring.
For cookies: balance leavening with acid source for predictable spread.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Expired leaveners can underperform even when measured correctly.
Brand Variance Example
Baseline on this page: 1 cup baking soda = 216g. Real-world range can shift by about 6% because fine powders and leaveners settle during storage, changing cup density.
Example for 2 cups: baseline 432g, common range 406g-458g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
