The BMI (Body Mass Index) calculator determines your body mass index based on your weight and height. It's a simple tool to check whether you are in a healthy weight range. The formula used is: BMI = weight (kg) / height² (m²).

Enter your weight in kilograms and your height in centimeters in the respective fields and click on 'Calculate BMI'. The calculator will display your Body Mass Index and indicate whether you are underweight, normal weight, overweight, or obese, based on standard BMI categories.
