How many cups are in a pound?

The conversion of cups and pounds will vary depending on the ingredient being used. A pound of sugar measures around 2.26 US cups, and a pound of flour measures around 3.62 US cups.

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.

I've listed below some common baking ingredients and their conversions. Please be aware that these approximations reference the US cup - different ingredient brands and cups sizes will vary. These measurements assume the ingredient is being spooned into the cup.
