1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It provides a simple numeric measure of a person's thickness or thinness.

\[ BMI = \frac{weight\ (kg)}{height\ (m)^2} \]

\( height \) — Height in meters

Explanation: The formula divides a person's weight in kilograms by the square of their height in meters.
