## What is BMI?

BMI (Body Mass Index) is a screening tool that uses height and weight to estimate body fatness. It's calculated as:

```
BMI = Weight (kg) / Height (m)²
```

## How to Use

1. Enter your weight (kg or lbs)
2. Enter your height (cm, m, or feet/inches)
3. View your BMI and category

## BMI Categories

| BMI Range | Category |
|-----------|----------|
| Below 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25.0 - 29.9 | Overweight |
| 30.0 and above | Obese |
