BMI Calculator - Calculate Body Mass Index Online Free

Understanding the Body Mass Index (BMI)

Body Mass Index (BMI) is a widely used screening tool that categorizes individuals into different weight classes based on their height and weight. While not a direct measure of body fat, it provides an easy-to-understand estimate that helps people identify if they are in a healthy weight range. Our BMI calculator is a simple, private way to track your health status from the comfort of your home.

Why is a BMI Calculator Useful?

Being underweight, overweight, or obese can increase the risk of various health conditions, including heart disease, type 2 diabetes, and high blood pressure. Monitoring your BMI periodically can motivate you to stick to your fitness goals or alert you to consult a healthcare professional about potential lifestyle changes.

2. Enter Height: Input your height in centimeters or feet/inches.
3. Calculate: The tool uses the formula weight(kg) / [height(m)]^2 to provide your score and category.
