How Body Mass Index (BMI) is Calculated
Body Mass Index (BMI) is an internationally recognized screening parameter established by the World Health Organization (WHO) to classify weight relative to height. Earnova Fit runs instant client-side biometric calculations using both Metric (cm/kg) and Imperial (ft/lbs) standards.
Official WHO Body Mass Index Classification
| Category | BMI Range (kg/m²) | Health Consideration |
|---|---|---|
| Underweight | < 18.5 | Potential nutritional deficit or underlying condition |
| Normal / Healthy | 18.5 – 24.9 | Optimal weight range for longevity and vitality |
| Overweight | 25.0 – 29.9 | Increased risk for cardiovascular conditions |
| Obese | >= 30.0 | Medical consultation recommended for tailored guidance |
