Convert Cups to Grams: Baking Powder

Convert cups of baking powder to grams with this complete reference table. 1 cup of baking powder = 230g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because baking powder density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Baking powder is a leavening agent. 1 teaspoon = 4.6g. Most recipes use teaspoon measurements. Check expiration — old baking powder loses potency. Do not substitute with baking soda without adjusting acid in recipe.

About Baking Powder Density

The density of baking powder determines how much it weighs per unit of volume. At 0.9g/ml, 1 US cup (240ml) of baking powder weighs 230g under USDA standard conditions.

Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.

Frequently Asked Questions

How many grams is 1 cup of baking powder?

1 cup of baking powder weighs 230 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).

How many grams is 1/2 cup of baking powder?

1/2 cup of baking powder weighs 115 grams.

How many grams is 1/4 cup of baking powder?

1/4 cup of baking powder weighs 58 grams.

Does measuring technique affect the weight of baking powder?

Yes. Sifted baking powder can weigh up to 20% less than packed or scooped. The USDA standard (spooned-and-leveled) of 230g/cup is the most reliable baseline.
