How Much Is 128 Grams of Baking Powder in Tablespoons?
128 grams of baking powder equals 8.90 tbsp. Baking powder has a density of 230g per cup. Because grams measure weight and tablespoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 128 grams of baking powder
- 1 cup of baking powder = 230g
- 128g ÷ 230g/cup = 0.56 cups × 16 = 8.90 tablespoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Leavener measurements are critical because even small differences affect rise and texture. When possible, weigh baking powder rather than relying on volume.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Tablespoon?
One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.
