Calculadora De Peso Altura

This calculator helps you determine your Body Mass Index (BMI) based on your weight and height. BMI is a widely used indicator of body fat based on height and weight that applies to adult men and women.

What is BMI?

The Body Mass Index (BMI) is a measurement developed by Belgian statistician Adolphe Quetelet in the 1830s. It 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.

BMI Formula

BMI = Weight (kg) ÷ (Height (m) × Height (m))

BMI is an inexpensive and easy screening method for weight categories that may lead to health problems. However, it measures body fat based on height and weight only and cannot distinguish between muscle, bone, and body fat.

How to use this calculator

Enter your weight in kilograms or pounds
Enter your height in centimeters or feet/inches
Click "Calculate" to get your BMI
Review the interpretation of your result

For best results, measure your weight without shoes and clothing, and your height while standing upright.

Interpreting your BMI

The BMI categories are defined as follows:

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

While BMI is a useful screening tool, it's important to remember that it doesn't measure body fat directly, and athletes or muscular individuals may have a higher BMI than expected.

Limitations of BMI

BMI has several limitations:

It doesn't distinguish between muscle, bone, and body fat
It doesn't account for age, sex, or body composition
It may not be accurate for children, pregnant women, or older adults
It doesn't measure visceral fat, which is more closely linked to health risks

For more accurate body fat measurement, consider using skinfold calipers or other body composition tests.
