1. What is IMC?

IMC (Índice de Massa Corporal) or BMI (Body Mass Index) 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 screening tool for weight categories.

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.

3. Importance of IMC Calculation

Details: IMC is important for assessing weight status and associated health risks. It helps identify underweight, normal weight, overweight, and obesity categories.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0).

Q2: Is IMC accurate for everyone?

Q4: What are the limitations of IMC?
A: IMC doesn't account for muscle mass, bone density, overall body composition, or racial and sex differences.

Q5: Should IMC be the only measure of health?
