Body Mass Index (BMI) Calculator

Body mass index (BMI) is a measure based on height and weight as it relates to body fat, and can be used to determine how much risk a person has to develop certain health problems because of his or her weight. As a point of reference, a person with a BMI of 27 is approximately 20 percent overweight. The higher the BMI, the greater the risk a person has to develop additional health problems.
