The short answer is that it depends on the powder.
For example, 1 lb of all purpose flour is approximately 4.5 U.S. cups while 1 lb of whole wheat flour is approximately 3.5 U.S. cups. I use "approximately" because how compacted the flour is will affect how much fits in a cup. Sifted flour has more volume than unsifted, for example.
But 1 lb of flour is still 1 lb of flour whether it is sifted or not. Because volume measures are so variable especially for powders, measuring by weight is what professional and expert bakers use.

One pound of dry lentils typically yields about 2.5 to 3 cups of cooked lentils. When cooked, lentils roughly triple in volume, so from one pound (which is approximately 2 cups dry), you can expect to get around 6 cups of cooked lentils. The exact amount can vary slightly depending on the type of lentils and the cooking method used.
One pound of dry grain typically equates to about 2 to 2.5 cups, depending on the type of grain and its density. For instance, one pound of rice is roughly 2.5 cups, while one pound of oats is closer to 3 cups. It's important to note that variations can occur based on the specific grain and its moisture content.
