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. If you want to check what sort of shape you're in, the Body Mass Index Calculator is a useful guide. It will tell you if you're a healthy weight for your height.
