1. What is IMC?

IMC (Índice de Massa 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 divides the weight by the square of the height to provide a standardized measure of body mass.

3. Importance of IMC Calculation

Details: IMC is important for assessing health risks associated with underweight and overweight conditions. It helps in identifying potential health problems and guiding weight management strategies.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). The calculator will provide your IMC and corresponding classification.

A: Below 18.5 (Underweight), 18.5-24.9 (Normal), 25-29.9 (Overweight), 30-34.9 (Obesity I), 35-39.9 (Obesity II), 40+ (Obesity III).

Q4: Can IMC be used for children?
A: For children and teens, BMI-for-age percentiles should be used instead of the standard IMC categories.
