1. What is BMI (IMC)?

BMI (Body Mass Index) or IMC (Índice de Masa Corporal) 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.

2. How Does the Calculator Work?

The calculator uses the BMI 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 BMI Calculation

Details: BMI is widely used as a screening tool to identify possible weight problems in adults. It helps assess health risks associated with underweight, normal weight, 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 precisely.

5. Frequently Asked Questions (FAQ)

Q1: What are the BMI categories?
A: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obesity (≥30).

Q2: Is BMI accurate for everyone?
A: BMI may not accurately reflect body fat in athletes, elderly, or those with high muscle mass as it doesn't distinguish between muscle and fat.

Q3: Can children use this calculator?

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

Q5: How often should I check my BMI?
A: For general monitoring, checking every 3-6 months is sufficient unless you're actively trying to change your weight.
