Measuring Baking Powder Accurately
Why weight matters: 1/2 cup of baking powder can weigh anywhere from 98g to 138g depending on how you measure it. The USDA standard is 115g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About baking powder density: 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 1/2 Cup as a Measurement
1/2 cup (120ml) is the most common single-serving measurement in baking. It equals 8 tablespoons or 24 teaspoons. Most standard muffin recipes call for 1/2 cup of flour per 6 muffins.
Half cup is a standard baking unit used in muffins, quick breads, pancakes, and cookie doughs. It represents exactly half of a US standard measuring cup (240ml).

How many grams is 1/2 cup of baking powder?
1/2 cup of baking powder weighs 115 grams (4.06 oz, 120ml). Based on USDA FoodData Central: 1 cup baking powder = 230g, so 1/2 cup = 230 × 0.500 = 115g.
Is 1/2 cup of baking powder the same weight every time?
The weight can vary slightly depending on measuring technique. Spooned and leveled gives 115g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 115g is the most reliable baseline for recipes.
How do I accurately measure 1/2 cup of baking powder?
For accuracy, use a kitchen scale and weigh 115g of baking powder. If using measuring cups, spoon the baking powder lightly into a 1/2 Cup measuring cup and level off the top with a straight edge. Avoid scooping directly from the container, which compacts the ingredient and adds extra weight.
How does 1/2 cup of baking powder compare to other ingredients?
1/2 cup of different ingredients varies significantly: Active Dry Yeast = 68g, Baking Powder = 115g, Baking Soda = 115g. This is because each ingredient has a different density.
