How to Calculate your BMI with a formula

Knowing your BMI, or Body Mass Index, is a great way to see if you are at a healthy weight. In this simple and short video provided by Children's Hospital Boston, you will figure out how to calculate your BMI by taking your weight (in pounds) and multiplying it by the number 703 and then dividing it by your height (in inches) squared.

Once you know your number, you can discuss it with your doctor and figure out which weight category you fall in, be it underweight, normal, overweight or obese.
