How many cups are in a pound?

If you want to know how many cups there are in a pound of flour, butter, sugar or any other baking ingredient, fear not. We've put together a table of cup measurements for one pound of each. We also have a handy converter at the top of the page.

If you're converting between pounds and cups, it's important to remember that the cup is a unit of volume and the pound (lb) is a unit of weight. This means that to make the conversion, you need a substance density figure.
