Baking powder:
grams to cups.
Baking powder weighs 192 g per cup, but it's almost never measured by the cup. Recipes use teaspoons and tablespoons — a teaspoon of baking powder weighs about 4 g, and getting that right matters more than almost any other ingredient because too much or too little directly controls how much your baked good rises.

Why baking powder is measured in teaspoons, not cups
Baking powder is used in small quantities because it's a concentrated leavening agent. A typical muffin recipe uses 1–2 teaspoons for a batter that makes 12 muffins. At that scale, even a small overcorrection — say, 1.5 teaspoons instead of 1 — adds 50% more leavening, which can cause the muffins to rise rapidly, then collapse as the structure fails to set before the bubbles deflate. Under-measuring baking powder produces dense, flat baked goods. Because a teaspoon of baking powder weighs about 4 g, a kitchen scale with 1 g precision is enough for accurate measurement.
Aluminum-free vs standard baking powder: different reaction timing, same density
Standard baking powder contains sodium aluminum sulfate as one of its acid components, which reacts with liquid during baking (double-acting). Aluminum-free baking powder uses cream of tartar or sodium acid pyrophosphate instead, producing a single-stage reaction at room temperature. Both types weigh approximately 4 g per teaspoon (192 g/cup) because the powders are similarly dense. The difference is in when the CO₂ is released, not in quantity — aluminum-free baking powder starts producing gas as soon as it hits liquid, so batters should be baked immediately after mixing. The density and gram conversions are the same for both types.
