In the BMI formula, what exponent is applied to height?

Explanation:
The exponent applied to height in the BMI formula is two. BMI is calculated as weight in kilograms divided by height in metres squared (BMI = weight / height^2). Squaring height helps normalize body size across people of different statures, since body dimensions don’t scale linearly with height. If height were not squared, or if a higher exponent were used, the BMI value would change too much with height, making it a poorer indicator of body fat for people who are shorter or taller.
