How To Calculate Body Mass Index (BMI)

In the metric system, BMI is calculated with the following formula:

BMI = Mass (kg) ÷ Height2 (m)

For you guys who are using the Imperial measurement system, simply multiply it by 703:

BMI = 703 X Mass (lbs) ÷ Height2 (in)

The resulting BMI will indicate whether a person is underweight, just right, or overweight.

Adapting the table from WHO again:
