How it works
BMI = weight (kg) ÷ height² (m), or 703 × weight (lb) ÷ height² (in).
BMI compares weight with height. It is a screening estimate, not a diagnosis.
Reference range
BMI = weight (kg) ÷ height² (m), or 703 × weight (lb) ÷ height² (in).
The BMI value places the entered measurements within a broad reference category. It is a screening indicator and does not account for muscle mass, body composition or individual medical context.
