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.
