* Pounds (lb) measure weight.
* Cups (c) measure volume.
To convert between pounds and cups, you need to know what you're measuring. For example:
* Flour: 1.5 pounds of flour is about 3.75 cups.
* Sugar: 1.5 pounds of granulated sugar is about 3.5 cups.
* Water: 1.5 pounds of water is equal to 1.5 cups (since 1 pound of water is 1 cup).
Let me know what you're trying to measure, and I can help you convert pounds to cups.
