Understanding Body Mass Index (BMI)
Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. It is defined as the body mass divided by the square of the body height, and is expressed in units of $\text{kg}/\text{m}^2$.
BMI Formula:
$$\text{BMI} = \frac{\text{Weight}}{\text{Height}^2}$$
WHO Standard BMI Categories:
| BMI ($\text{kg}/\text{m}^2$) | Weight Status |

| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and Above | Obesity |
