Work out your Body Mass Index from height and weight, in either metric (cm/kg) or imperial (ft-in/lb) units, using the standard WHO formula.
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
BMI is a simple screening measure, not a diagnosis — it doesn't distinguish muscle from fat and can be misleading for athletes, older adults, or during pregnancy. Talk to a doctor for a proper health assessment.
