Common Mistakes People Make

Confusing pounds with stone. Stone is another UK measurement. 100 kg equals about 15.75 stone, not 220 stone. If someone tells you they weigh 220 stone, they're either lying or from another planet.

Forgetting the decimal. 100 kg is 220 lbs, not 22 lbs. That's a 10x difference. Double-check your decimal point.

Using the wrong conversion rate. Some old references use 2.2, which is fine for estimates. But if you're shipping freight or calculating medication doses, use the full 2.20462 for accuracy.
