1. What is Body Mass Index (IMC)?

Body Mass Index (IMC) 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 in kilograms by the square of height in meters.

3. Importance of IMC Calculation

Details: IMC is an important screening tool to identify potential weight problems in adults. It helps assess health risks associated with underweight, overweight, and obesity.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For accurate results, measure weight and height without shoes and in light clothing.
