Calculadora de IMC — Índice de Masa Corporal Gratis

BMI (Body Mass Index) is a widely used screening tool that provides a quick estimate of body composition based on height and weight. While it is not a perfect measure of health, it serves as a useful starting point for conversations about weight management. Nuestro/a BMI Calculator gives you ynuestro/a number instantly with context on what it means.

¿Qué es BMI?

Body Mass Index is calculated by dividing a person's weight in kilograms by the square of their height in meters: BMI = kg/m². The result falls into categories: underweight (below 18.5), normal weight (18.5-24.9), overweight (25-29.9), and obese (30 and above). These ranges were established by the World Health Organization.

Casos de Uso Comunes

Individuals tracking their fitness journey calculate BMI periodically to monitor progress. While BMI should not be the sole metric, it provides a simple, objective number that is easy to track over time.

Health professionals use BMI as an initial screening tool during patient assessments. It flags potential weight-related health risks that warrant further evaluation with more detailed measures.

Life insurance applicants check their BMI before applying, as many insurers use BMI ranges to determine premium rates.

Consejos y Buenas Prácticas

• BMI does not distinguish between muscle and fat mass. Athletes and muscular individuals often have a "high" BMI despite being healthy.
• BMI categories do not account for age, sex, or ethnicity. The same number may indicate different risk levels for different populations.
• Use BMI as one data point among many — not a definitive health verdict. Waist circumference, body fat percentage, and blood markers provide a more complete picture.

Preguntas Frecuentes

What is a healthy BMI range?

A BMI of 18.5-24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is classified as obese. However, BMI does not account for muscle mass, bone density, or body composition.

Is BMI accurate for athletes?

No. BMI often misclassifies muscular individuals as overweight or obese because it cannot distinguish between muscle and fat mass. Body fat percentage is a more meaningful metric for athletes and regular exercisers.

How is BMI calculated?

BMI is calculated by dividing weight in kilograms by height in meters squared: BMI = kg / m². For imperial units: BMI = (weight in pounds × 703) / (height in inches)².
