Calculate your Body Mass Index

Calculate your Body Mass Index

Monday, July 6, 2009

The Body Mass Index (BMI) is used to estimate the body fat percentage. It is defined as the individual's body weight divided by the square of his or her height.

BMI = Weight (Kg)/Height2 (Metres2)

Use the calculator on the top right to calculate your BMI!

This measurement is not very accurate as it doesn't consider the age or properties of special groups as body builders, elderly people, pregnant women, children, or people with physical disabilities. However it is a useful tool to estimate a healthy body weight (BMI between 20 and 25).

Category BMI range – kg/m2
Severely underweight less than 16.5
Underweight from 16.5 to 18.5
Normal from 18.5 to 25
Overweight from 25 to 30
Obese Class I from 30 to 35
Obese Class II from 35 to 40
Obese Class III over 40
