BMI Range

How It Works

The Body Mass Index (BMI) is calculated using your height and weight to determine if you're in a healthy weight range. The formula used is:

BMI = weight (kg) / (height (m))²
For imperial units: BMI = (weight (lb) / (height (in))²) × 703

BMI Categories:

  • Underweight: Less than 18.5
  • Normal weight: 18.5 to 24.9
  • Overweight: 25 to 29.9
  • Obese: 30 or greater

Note: BMI is a general guide and may not be accurate for athletes, elderly people, or during pregnancy.
