Body Mass Index Calculator


 

Calculate Your Body Mass Index (BMI)

Your Body Mass Index (BMI) is a relationship between your height and weight. When your BMI is computed, a value is assigned, which is a relationship or ratio comparing
  • Your Height
  • Your Weight

 

How the Calculator Works

 

Your weight is converted into kilograms and then divided by the square of your height, measured in meters.

For example, if your height is 1.80 meters and you weigh 69.5 kilograms
  • Your height (1.80 meters) is multiplied by itself, (1.80 * 1.80) = 3.24
  • Your weight (69.5 kg) is divided by the result of the above calculation, (69.5 divided by 3.24)
  • Your BMI is 21.45

 

What is the Significance of Your BMI?

Individuals with BMIs between 19 and 22 live longest. People with BMIs above 25 have noticeably higher death rates. A BMI over 40 is considered clinically severe obesity. Surgery should be considered for patients with a BMI over 35 when co-morbid conditions are present.
