About BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight. It's a useful screening tool to identify potential weight-related health problems.

How BMI is Calculated

Metric: BMI = weight (kg) / height (m)²

Imperial: BMI = (weight (lbs) / height (inches)²) × 703

Important Notes

  • BMI is a screening tool and not a diagnostic tool
  • It may not be accurate for athletes with high muscle mass
  • Age, gender, and ethnicity can affect BMI interpretation
  • Consult with a healthcare provider for personalized advice
