Body mass index calculator

Your body fat can be determined by a measurement called body mass index (BMI), which is based on weight and height. Using the Healthy People 2010 standards (HP2010), all adults with a BMI between 25 and 29.9 are classified as being overweight and those with a BMI over 30 are considered obese.
