Grams to cups: baking powder

Working the other way — a recipe in grams, and cups are what you have in the drawer:

Grams of baking powder	Cups (approx.)
50 g	¼ cups
100 g	½ cups
125 g	⅔ cups
200 g	1.04 cups
250 g	1⅓ cups
500 g	2⅝ cups

Why the measuring method matters

The 192 g figure assumes baking powder measured 4 g per tsp. Volume measurement is sensitive to how the cup is filled — packing or scooping changes how much fits, which is why the same "1 cup" can vary noticeably between two bakers. A scale removes the variable entirely, and it is the reason professional recipes are written in weight.

Frequently Asked Questions

How many grams is 1 cup of baking powder?

One US cup of baking powder weighs 192 grams (about 6.77 ounces), measured 4 g per tsp. This follows the King Arthur Baking ingredient weight chart, the reference most US test kitchens use.

How many grams is a tablespoon of baking powder?

A tablespoon of baking powder is about 12 grams, since one cup holds 16 tablespoons. A teaspoon is about 4 grams.

How many cups is 250 g of baking powder?

250 grams of baking powder is about 1⅓ cups (250 ÷ 192). Weighing is more reliable than measuring by cup, because how you fill the cup changes the amount.

Does how I measure baking powder change the weight?

Yes — this figure assumes 4 g per tsp. Scooping straight from the bag compacts baking powder and can add a noticeable amount of extra weight per cup, which is exactly why recipes written in grams are more repeatable.
