Why Convert Weight?
Before jumping into the conversion process, let's understand why you might want or need to convert between pounds and kilograms.

The Conversion Formula
Converting pounds to kilograms is straightforward once you know the formula:
$ \text{kg} = \text{lbs} \times 0.45359237 $
However, to make it simple, we generally round this conversion factor to 0.454 for quick manual calculations:
kg = lbs * 0.454
Practical Example
Let's take our example of 180 lbs:
kg = 180 * 0.454
