## Explanation

Devised all the way back in way back in 1830, the Body Mass Index is a single figure used to as a way of measuring a person's body shape. Put simply, it is calculated by dividing the body's weight by the square of their height. Eg: Kilograms: weight, divided by Metres (Meters): height. This app will calculate your body mass index and tell you if you are underweight, overweight or if your weight is optimal. Just enter your vital statistics and click the button. Your result will be shown on a graph for you. ## The maths

The formula below is used to measure BMI

- BMI = weight(kilograms) / height
^{2} (metres^{2}) (Metric Units) - BMI = 703 . weight(pounds) / height
^{2} (inches^{2}) (Imperial Units)

## BMI limitations

BMI is proportional to the mass and inversely proportional to the square of the height. So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.
