Understanding Pounds (lbs) vs Kilograms (kg)
Before diving into the conversion tricks, it's vital to grasp the basic differences between these units of measure:
- Pound (lb): A unit of weight primarily used in the United States, and to some extent, the United Kingdom. 1 pound is equal to 16 ounces.
