How BMI Calculation works
The BMI Calculator computes your Body Mass Index using your height and weight. BMI is a widely-used screening tool that categorizes weight status into underweight, normal, overweight, and obese ranges. It supports both metric (kg/cm) and imperial (lbs/inches) measurement systems.
