Understanding Pounds and Kilograms
What are Pounds?
The pound (symbol: lb or lbs) is a unit of weight used predominantly in the United States, the UK, and Canada. Originally defined by the weight of water or grains, its exact value has changed over time, but today it's standardized as:

- 1 pound ≈ 0.45359237 kilograms
What are Kilograms?
The kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It's more commonly used worldwide than the pound. The kilogram is defined by fixing the numerical value of the Planck constant, but practically:
- 1 kilogram ≈ 2.20462 pounds
