What is BMI and How is it Calculated?
Body Mass Index (BMI) is a numerical indicator used to evaluate the ratio of body mass to height. BMI is calculated using the following formula:
BMI = weight (kg) / (height (m))²
For example, if your weight is 70 kg and your height is 175 cm (1.75 m), then your BMI would be: 70 / (1.75 * 1.75) ≈ 22.86
Interpreting BMI Results
After calculating your BMI, you can determine which category your weight falls into:
| Category | BMI |
|---|---|
| Underweight | Less than 18.5 |
| Normal weight | 18.5 - 24.9 |
| Overweight | 25 - 29.9 |
| Obesity Class I | 30 - 34.9 |
| Obesity Class II | 35 - 39.9 |
| Obesity Class III | 40 and above |
Why is it Important to Know Your BMI?

Limitations of BMI
It’s important to remember that BMI has some limitations:

- It may be inaccurate for athletes, elderly people, and children
- It doesn’t reflect fat distribution in the body
