## How BMI is Calculated
Example Calculations:
- COnsidering **Adult Male (25 years, 178 cm, 69.8 kg):**
- BMI = 24.2 (Normal weight)
- Considering **Adult Female (35 years, 162.5 cm, 59.9 kg):**
- BMI = 22.1 (Normal weight)
- Considering **Child (10 years, 142.5 cm, 38.6 kg):**
- BMI-for-age percentile = 50th percentile (Normal weight)
