How many cups are in a pound?
The conversion of pounds to cups varies depending on the ingredient you're measuring. A pound of sugar equates to around 2 1/4 US cups, and a pound of flour measures around 3 2/3 US cups. This is because sugar is denser thant flour (hence it weighs more).
When 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. To convert between the two requires an ingredient density figure to be factored in.
I've listed below some common baking ingredients and their pound (lb) to cup conversions. These approximations reference both the US cup (236.6 mL) and metric cup (250 mL). Note that different ingredient brands may vary slightly.

These measurements assume the ingredient is being spooned into the cup. If you're using the dip and sweep method, consider reducing by 15-20%.

Which cup is which?
As you'll have noticed from the list of conversion options above, there are different types of cup depending on where in the world you are. The cup is more commonly referenced in US recipes than the rest of the world.
