Answer 2

BMI is not intended for guaging health and fitness. It's a terrible measure of body composition as well. The only real way of guaging body composition (percentage of bodyfat) is through total water immersion. The next best thing to that would be to have a health professional use a tape measure and calipers, though this method isn't nearly as accurate as water immersion, but still far superior than BMI. BMI is intended primarily for measuring central obesity.

Answer 3

Body Mass Index=
weight (kg) divide it by your height squared (meters squared)

Answer 4

Have a look at the link below - enter the info in the boxes and it spits it out for you.

It also provides a legend to what BMI means, ie.:

BMI Categories:
Underweight = <18.5
Normal weight = 18.5-24.9
Overweight = 25-29.9
Obesity = BMI of 30 or greater

Easy peasy...

Answer 5

It is your weight in kilograms divided by your height squared in meters squared.

This is not very accurate because it would indicate an extremely lean bodybuilder as being obese.

Here is an article about measuring body composition:

Answer 6

unless you are overweight and heading towards obesity the BMI is meaningless. the "only" purpose of the BMI is to address the risk factor that is associated with central obesity, a low BMI is not an indicator of good health just not a risk for central obesity.

body composition (body fat) is all that matters, total bodyweight is irrelevant.

Answer 7

It is your height divided by your weight.
