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.

Formula

BMI = Weight (kg) / Height (m)\u00b2 \u2014 or \u2014 BMI = (Weight (lbs) \u00d7 703) / Height (inches)\u00b2

Key Features

  • Supports both metric and imperial units
  • Instant BMI category classification with color coding
  • Based on WHO standard BMI ranges
  • Easy unit switching for international users

Pro Tip

BMI is a useful screening tool but does not account for muscle mass, bone density, or body composition. Athletes with high muscle mass may have elevated BMI readings despite being in excellent health.
