Imperial BMI Calculator

The body mass index (BMI) is widely used to determine an individual's ideal body weight. Similar to the height and weight chart, it is essentially the relationship between a person's weight and height. The BMI calculator provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems. The BMI formula is BMI=kg/m2. That means body mass index equals a person's weight in kilograms divided by height in meters squared.
