A measure of body weight relative to height. BMI can be used to determine if people are at a healthy weight, overweight, or obese. To figure out BMI, use the following formula:
Weight in pounds x 703 / Height in Inches x Height in Inches = BMI
A body mass index (BMI) of 18.5 up to 25 refers to a healthy weight, a BMI of 25 up to 30 refers to overweight and a BMI of 30 or higher refers to obese.
