BMI stands for body mass index. It is a number that tells whether your weight is appropriate for your height. BMI tells whether you are overweight, underweight, or have a healthy weight. Your weight (in kilograms) is divided by the square of your height (in metres) to get your BMI.

Why Use the BMI Calculator
Body mass index (BMI) is a simple and effective way to understand whether a person is obese or lean. BMI estimates body fat content based on weight and height. There are many benefits of using it:
BMI tells whether your weight is in a healthy range or not. If BMI is too high, it can be a sign of obesity, which increases the risk of many serious diseases like heart disease, diabetes, high blood pressure. At the same time, a very low BMI also indicates weakness and lack of nutrition.
BMI is used by doctors and health experts to understand your health status and give correct advice. It is an easy way to conduct large-scale health surveys and awareness campaigns.
With BMI, you can also monitor your health yourself and make lifestyle changes if needed, such as better eating habits and regular exercise.
Therefore, the use of BMI is very important to control health and adopt a better lifestyle. It not only gives you information about your health, but also helps you move in the right direction.
