simply divide pounds by 2.2 to get Kg!
for example, i am a stocky 170 lbs at home but 85 Kg in the rest of the world!
or for another example Prince weighs 120 lbs so he is 54.50 Kgs!
or founding father Benjamin Franklin weighed 235lbs so he was 107 Kgs!
Yolanta Drabik is from france and she weighs 54 Kgs! perfect!
