How to Compute BMI Online

BMI, or body mass index, is a metric used in the medical field to predict your risk for obesity-related diseases. The formula requires your height and weight. However, since the formula cannot account for your body composition, BMI can be misleading for people with significant muscle mass, such as athletes and body builders. If you do not want to calculate your BMI by hand, you can use an online calculator.
