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
