What is Body Mass Index (BMI)

Body Mass Index Calculator
Body Mass Index (BMI) is a measure of body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in meters (BMI=kg/m2)

BMI = body weight in kilograms/height in meters squared


BMI
Normal: 18.5 - 24.9
Overweight: 25 - 29.9
Obese: 30 and over

A BMI of between 18.5 to 25 is considered normal.
A BMI of over 25 is considered overweight
A BMI of over 30 is considered obese.

This is not applicable for all circumstances. The exceptions to this rule are body builders(or someone with very muscular body ), trained athlete, pregnant women, and those with massive obesity.
NOTE : BMI is not particularly accurate measure because it does not differentiate muscle mass from fat mass.
