Calculadora Peso Altura

This calculator helps you determine your Body Mass Index (BMI) by entering your weight and height. BMI is a widely used indicator of whether a person has a healthy body weight for their height.

What is BMI?

The Body Mass Index (BMI) is a simple calculation that relates a person's weight to their height. It's commonly used as a general indicator of whether a person has a healthy body weight for their height.

BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. The result is a numerical value that can be used to categorize a person's weight status.

BMI is not a direct measure of body fat. It's a screening tool that can help identify potential weight-related health issues, but it doesn't measure body composition or body fat percentage.

How to Use This Calculator

Enter your weight in the weight field (in kilograms or pounds)
Enter your height in the height field (in centimeters or feet/inches)
Click the "Calculate" button
View your BMI result and category

For example, if you weigh 70 kilograms and are 170 centimeters tall, your BMI would be calculated as follows:

BMI = 70 ÷ (1.7 × 1.7) = 24.22

This would place you in the "Normal weight" category.

BMI Formula

The formula for calculating BMI is:

BMI = weight (kg) ÷ (height (m) × height (m))

For imperial units (pounds and inches):

BMI = (weight (lb) ÷ (height (in) × height (in))) × 703

Where:

weight is your body weight in kilograms or pounds
height is your height in meters or inches

BMI Categories

The following table shows the standard BMI categories:

BMI	Category
Below 18.5	Underweight
18.5 - 24.9	Normal weight
25 - 29.9	Overweight
30 or higher	Obesity

These categories are general guidelines and may not apply to everyone, especially athletes or people with significant muscle mass.

Limitations of BMI

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

It doesn't distinguish between muscle and fat
It may not be accurate for athletes or people with high muscle mass
It doesn't account for age, sex, or overall body composition
It may not be appropriate for children or adolescents

For a more accurate assessment of body composition, consider using other methods such as body fat percentage measurements or DEXA scans.

Frequently Asked Questions

What is a healthy BMI?

A BMI between 18.5 and 24.9 is generally considered healthy. However, this range may not be appropriate for everyone, especially athletes or people with significant muscle mass.

Can BMI be used for children?

BMI is not recommended for children under 2 years old. For children and adolescents, specialized growth charts should be used instead of BMI.

Is BMI accurate for athletes?

BMI may not be accurate for athletes or people with high muscle mass, as muscle weighs more than fat. Athletes may have a higher BMI but still be in good health.

What should I do if my BMI is outside the healthy range?

If your BMI is outside the healthy range, consider consulting with a healthcare professional. They can provide personalized advice and help you develop a healthy lifestyle plan.
