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.

The calculator uses the BMI equation:

Where:

• \( weight_{kg} \) — Weight in kilograms
• \( height_m \) — Height in meters (1.626m for 5'4")

Explanation: The equation divides weight by the square of height to account for the relationship between height and body surface area.
