What is BMI?

BMI (Body Mass Index) is a measurement that helps estimate how healthy your body is based on your weight and height.


How is my BMI Calculated?

After inputting your height and weight your BMI is calculated using a formula:

Metric:   weight(kg)/height2(m)
Imperial:   703*weight(lb)/height2(in)

In addition to outputting the number, the program also follows this chart for the “You Are” result it outputs:

Underweight Less than 18.5
Normal Between 18.5 and 25
Overweight Between 25 and 30
Obese Over 30
