BMI Calculator
Body Mass Index estimates whether your weight is in a healthy range relative to your height.
About BMI
Body Mass Index (BMI) is a simple calculation using height and weight. The result places you in one of the WHO's standard categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 – 34.9 | Obese (Class I) |
| 35.0 – 39.9 | Obese (Class II) |
| 40.0+ | Obese (Class III) |
BMI is a useful screening tool but has limitations: it does not distinguish between muscle and fat, and very muscular individuals may register as overweight without having excess body fat.
Formula:
BMI = weight (kg) / (height (m))²
