Features
- Body Mass Index from weight and height (metric or imperial)
- WHO BMI categories: underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), obese (≥30)
- Inline conversion between kilograms / pounds and centimetres / inches
- Healthy weight range computed for your height
- Everything runs in your browser; weight and height are never uploaded
Tips & Best Practices
- BMI is a screening number, not a diagnosis — it does not account for muscle mass or body composition.
- Switch between metric and imperial inputs at the top; the formula stays the same internally (kg / m²).
- The healthy-range result is derived from your height; treat it as guidance, not a target.
- Athletes with high muscle mass often score "overweight" on BMI; that's a known limitation of the index.
- For medical advice consult a clinician — this tool computes the formula, nothing more.
