IMC (Índice de Masa Corporal) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple and widely used method to classify underweight, normal weight, overweight, and obesity.

2. How Does the Calculator Work?

The calculator uses the IMC formula:

Where:

• \( peso \) — Weight in kilograms (kg)
• \( altura \) — Height in meters (m)

Explanation: The formula calculates body mass index by dividing weight by the square of height.
