Body Mass Index Calculator (BMI calculator)

The BMI calculator is a simple yet powerful tool that helps you estimate your body mass index based on your weight and height. By using a BMI calculator, you can quickly determine whether you fall into the underweight, normal weight, overweight, or obese category.
Healthcare professionals often recommend the BMI calculator for quick screening during medical check-ups and research studies.
For postgraduate medical students, the BMI calculator is also a useful addition to thesis work, allowing them to collect and interpret anthropometric data easily. Whether you are a patient, student, or researcher, a BMI calculator can help you understand and monitor your health status effectively.
