DETAIL:
A 100 kilogram person who is 2.5 metres tall will have a lower BMI than a person of the same weight but who is only 1.5 metres tall. The BMI measurement is only accurate for adult men and women who have stopped growing. A higher BMI usually indicates that you are overweight or obese. But this is not always the case because muscle mass is heavier than body fat. On average, the density of fat is 0.9g/ml, whereas the density of muscle is 1.1 g/ml.
To calculate your BMI
1) Find your weight in Kilograms
2) Measure your height in metres
3) Calculate the square of your height
4) Divide your weight by the value you calculated in 3).
For example:
1) 100 Kg 2) 2.5 metres 3) 2.5 X 2.5 = 6.25 4) 100 / 6.25 = 16
2) 100 Kg 2) 1.5 metres 3) 1.5 X 1.5 = 2.25 4) 100 / 2.25 = 44.4
