Baking powder, Cups to Grams & Grams to Cups
1 cup of baking powder = 192 grams · 100g = 0.52 cups
Baking powder is a complete leavener — baking soda plus a built-in acid — and like baking soda it is used by the teaspoon (about 4g each) rather than the cup. A full cup weighs around 192 grams. Most modern baking powder is double-acting, releasing gas both when wet and when heated.

Baking powder: US, metric & UK cups compared
A “cup” isn’t the same size everywhere, so 1 cup of baking powder weighs a different number of grams depending on which cup your recipe uses. The US cup is 236.6 ml, while Australia, New Zealand, Canada and modern UK recipes use a 250 ml metric cup. Here’s 1 cup of baking powder in each:
| Cup standard | Size | 1 cup baking powder | Used in |
|---|---|---|---|
| US cup | 237 ml | 192 g | United States (most US recipe sites) |
| Metric cup | 250 ml | 203 g | Australia, NZ, Canada & modern UK |
| UK imperial cup | 284 ml | 231 g | Older British recipes |
| Japanese cup | 200 ml | 162 g | Japan |
Unless a recipe says otherwise, US recipes mean the US cup and Australian/UK recipes mean the 250 ml metric cup. The tables higher up this page use the US cup.

Because one cup of baking powder weighs about 192 grams, you can convert any weight to cups by dividing by 192. So 100g of baking powder is about 0.52 cups, 200g is about 1.04 cups, 250g is about 1.3 cups, and 300g is about 1.56 cups. For any other amount, type the grams straight into the converter above and switch it to show cups.
How to measure baking powder accurately
For the most reliable baking results, weigh baking powder on a kitchen scale rather than scooping by volume. One US cup of baking powder weighs about 192 grams (6.77 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts baking powder and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Baking powder loses potency over time; test it by stirring a teaspoon into hot water — it should fizz vigorously. If it barely bubbles, replace it.
