Calculate your Body Mass Index to assess whether your weight is in a healthy range.
A BMI calculator computes your Body Mass Index to classify your weight relative to your height. The formula used is:
WHO categories: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), Obese (≥30). For example, a person weighing 70 kg and 1.75 m tall has a BMI of 22.86 (Normal).
| Category | BMI Range |
|---|---|
| Underweight | < 18.5 |
| Normal weight | 18.5 – 24.9 |
| Overweight | 25.0 – 29.9 |
| Obesity Class I | 30.0 – 34.9 |
| Obesity Class II | 35.0 – 39.9 |
| Obesity Class III | ≥ 40.0 |
