Divide the gram amount by 192 to calculate US cups. The practical fraction is a measuring aid, not a replacement for the exact gram weight.
| Grams | US cups | Practical reference |
|---|---|---|
| 25 g | 0.13 cups | about 1/8 cup |
| 30 g | 0.16 cups | about 1/8 cup |
| 40 g | 0.21 cups | about 1/4 cup |
| 50 g | 0.26 cups | about 1/4 cup |
| 60 g | 0.31 cups | about 1/3 cup |
| 75 g | 0.39 cups | about 1/3 cup |
| 80 g | 0.42 cups | about 1/2 cup |
| 100 g | 0.52 cups | about 1/2 cup |
| 120 g | 0.62 cups | about 2/3 cup |
| 125 g | 0.65 cups | about 2/3 cup |
| 150 g | 0.78 cups | about 3/4 cup |
| 200 g | 1.04 cups | about 1 cup |
| 250 g | 1.30 cups | about 1 1/3 cups |
| 300 g | 1.56 cups | about 1 1/2 cups |
| 400 g | 2.08 cups | about 2 cups |
| 500 g | 2.60 cups | about 2 2/3 cups |
Spoon it into the measuring spoon and level with a straight edge. Do not scoop from the tin, which compacts it. Baking powder also loses strength over time, so an old tin measured perfectly still underperforms.
Grams = cups × 192
One cup is 192 grams, one-half cup is about 96 grams and one-quarter cup is about 48 grams.
Common uses
- Oatmeal and overnight oats
- Granola
- Cookies and crumble toppings
Baking powder and baking soda are not interchangeable, by weight or by volume. Soda is roughly four times stronger and needs an acid in the recipe to work.
| Type | Grams per US cup | What changes |
|---|---|---|
| Baking powder | 192 g | The reference on this page. 4 g per teaspoon. |
| Baking soda | 288 g | 6 g per teaspoon, and about four times stronger. |
| Cream of tartar | 144 g | 3 g per teaspoon. |
| Instant yeast | 150 g | A different kind of leavening entirely. |
Substituting baking soda for baking powder teaspoon for teaspoon makes a batter soapy and metallic. The usual conversion runs the other way: one part soda plus two parts cream of tartar makes three parts baking powder.
Comparison figures are typical published US baking references. Only the baking powder value above is part of this site's sourced dataset.
Baking powder is almost always measured in teaspoons; the cup figure is a reference, not an instruction. The value on this page names the exact product state it applies to, so you can check it against your own ingredient rather than trusting a bare number.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.

How many grams are in one cup of baking powder?
One US cup of double-acting baking powder, levelled weighs 192 grams.
How many cups is 100 grams of baking powder?
100 grams of baking powder is 0.52 US cups.
How many grams is half a cup of baking powder?
Half a US cup is about 96 grams using the 192 gram full-cup reference.
How many grams is a teaspoon of baking powder?
About 4 grams, spooned in and levelled.
Is baking powder the same weight as baking soda?
No. A teaspoon of baking soda is about 6 grams against 4 grams for baking powder, and soda is considerably stronger, so the two are never interchangeable.
Are these US cups or metric cups?
The results use a US customary cup of 236.588 millilitres. A metric cup is 250 millilitres and gives a different answer.
