Body mass index (BMI) calculator

The Body Mass Index (BMI) calculator is a tool designed to determine whether you are underweight, normal weight, overweight, or obese. It evaluates your weight status by analyzing the relationship between your height and weight, providing a reliable indication of whether your weight falls within a healthy range.

The calculation is as follows:

Body Mass Index (BMI) = Height in meters X Height in meters / Body weight in kilograms

The BMI calculator determines your Body Mass Index (BMI), a measure of body fat based on the relationship between your height and weight. It is applicable to adult men and women, providing insight into whether your weight falls within a healthy range.

The BMI calculator works by dividing your weight in kilograms by the square of your height in meters to determine your BMI value. The formula can be expressed as:
BMI = Weight (kg) / [Height (m)]²
This equation provides a numerical representation of your body mass, allowing you to assess if your weight is within a healthy range.

Body mass index = weight in kilograms / height in meters squared.

This value is commonly used as an indicator of whether a person has a healthy weight relative to their height. Based on the resulting value, individuals can be classified as underweight, normal weight, overweight, or obese, depending on which range their BMI falls into.

It is important to note that BMI is an imperfect measure of healthy body weight, as it does not account for factors such as muscle mass or body composition. However, it serves as a useful initial screening tool to help determine if further evaluation or testing is needed.
