9 stone 4 in pounds is 130 pounds. The calculation follows the rule that there are 14 pounds in every stone. The average weight of a woman in the United Kingdom is currently 11 stone (154 pounds).
The heaviest person the world has ever seen
The heaviest person ever recorded came in the form of Jon Brower Minnoch, weighing in at a staggering 100 stone. That's 1,400 pounds! What I find even more disturbing, however, is that Jon Minnoch weight 21 stone by the time he was 12 years of age. Of course, being so heavy was highly detrimental to his health, and he died on 10th September, 1983 at the age of 41.
The lightest adult the world has ever seen
The lightest adult person ever recorded is Lucia Zarate. I find this unbelievable, but she weighed a total of 4.7 pounds, and was only 21.5 inches tall. If you are struggling to imagine that, it is said that her calf muscle was the same size as the average males thumb!
