Calculador Peso

El índice de masa corporal (IMC) es una medida común para evaluar si una persona tiene un peso saludable. Este calculador de peso te permite calcular tu IMC y determinar tu categoría de peso basada en tu altura y peso.

What is BMI?

The Body Mass Index (BMI) is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m², resulting from mass in kilograms and height in metres.

Formula

BMI = Peso (kg) / (Altura (m) × Altura (m))

BMI is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight, and obesity in adults. It is not a direct measure of body fat, but it is a useful screening tool for identifying individuals who may be at risk for health problems related to weight.

BMI Categories

The following table shows the BMI categories for adults:

BMI	Category
Below 18.5	Underweight
18.5 - 24.9	Normal weight
25.0 - 29.9	Overweight
30.0 and above	Obesity

Note: BMI is not a perfect measure of body fat, especially for athletes or individuals with high muscle mass. It's important to consider other factors such as waist circumference and body composition when evaluating health.

How to use this calculator

Enter your weight in kilograms in the "Peso" field.
Enter your height in meters in the "Altura" field.
Click the "Calcular" button to calculate your BMI.
Review your results and interpretation.

Example Calculation

If you weigh 70 kg and are 1.75 meters tall:

BMI = 70 / (1.75 × 1.75) = 22.86

This would classify as "Normal weight" according to the BMI categories.

How to interpret your results

Your BMI result will be classified into one of the following categories:

Underweight: BMI below 18.5 - You may need to gain weight.
Normal weight: BMI 18.5-24.9 - You have a healthy weight.
Overweight: BMI 25.0-29.9 - You may need to lose weight.
Obesity: BMI 30.0 and above - You may need to lose significant weight.

Remember that BMI is just one measure of health. Other factors such as muscle mass, bone density, and overall body composition should also be considered.

Limitations of BMI

While BMI is a useful screening tool, it has several limitations:

It doesn't distinguish between muscle and fat.
It doesn't account for differences in body composition.
It may not be accurate for athletes or individuals with high muscle mass.
It doesn't consider other health factors like waist circumference.

For a more accurate assessment of body fat, consider using other measures such as body fat percentage or waist-to-hip ratio.
