There is no "pound kg ratio" because pounds (lb) and kilograms (kg) are units of weight or mass, not a ratio.

Here's the conversion between pounds and kilograms:

* 1 kilogram (kg) = 2.20462 pounds (lb)

Therefore, to convert pounds to kilograms, divide the weight in pounds by 2.20462.

To convert kilograms to pounds, multiply the weight in kilograms by 2.20462.
