Calculate your Body Mass Index (BMI) accurately with our clinical-grade tool. Based on WHO and NIH standards.
Weight: 70 kg, Height: 175 cm → BMI: 22.9 (Healthy Weight (18.5–24.9))
BMI = weight (kg) / [height (m)]²
BMI = 703 × (weight (lbs) / height (in)²)
| Category | BMI Range | Health Context |
|---|---|---|
| Underweight (<18.5) | < 18.5 | Under 18.5: Risks include osteoporosis and weakened immunity. |
| Healthy Weight (18.5–24.9) | 18.5–24.9 | 18.5–24.9: Lowest risk of cardiovascular diseases. |
| Overweight (25–29.9) | 25–29.9 | 25–29.9: Increased visceral fat risk. |
| Obese (≥30) | ≥ 30 | ≥30: High risk of hypertension and type 2 diabetes. |
BMI doesn't distinguish muscle from fat. This means athletes might be misclassified as overweight. See WHO adjustments for specific demographics.
For Asian populations, health risks begin at a lower BMI (23 instead of 25). For seniors over 65, a slightly higher BMI (25-27) may offer protective benefits against mortality.
