BMI Calculator


Body mass index (BMI) is an approximation of an average adult's body fat by calculating a ratio between your weight and your height. While it is a good estimation for most people, it is rather inaccurate for people with low body fat or who are muscular. You should take this value as a suggestion and not as the absolute truth.

Usage:

Enter your height and weight and your BMI will be automatically calculated.
