The Body mass index is calculated by dividing a person’s weight by the square of his or her height (kilos/(metres)2).The larger it is the heavier you are. This web page is based on the growth charts for American children. It is NOT designed to tell you if you are UNDERWEIGHT only if you are NOT OVERWEIGHT, at risk of being OVERWEIGHT or OVERWEIGHT.
For further information please visit the US government growth charts web site.
