How to Use BMI Calculator
The BMI Calculator is a free online tool that calculates your Body Mass Index from your height and weight measurements. BMI is a widely used screening measure that indicates whether your weight is in a healthy range relative to your height. Enter your weight in kilograms and height in centimeters, and the calculator instantly shows your BMI value along with the corresponding category (underweight, normal weight, overweight, or obese). The formula used (weight divided by height squared) is displayed for transparency. While BMI is a useful general indicator, remember it does not account for muscle mass, bone density, or body composition.
