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.
It depends on the density of what you are attempting to measure
