What is The BMI Formula and How is Calculated? 

Metric Units: BMI = Weight (kg) / (Height (m) x Height (m))

English Units: BMI = Weight (lb) / (Height (in) x Height (in)) x 703


Both BMI and body fat percentage give valuable health information.  BMI is an equation that gives you a numerical rating of your health based on height and weight. As your BMI goes up, so does your risk of developing weight-related diseases, such as heart disease and diabetes.

Research is improving, though, about how body fat percentage relates to disease.  In September 2000, the American Journal of Clinical Nutrition published a study showing that body-fat percentage may be a better measure of your risk of weight-related diseases than BMI.
