Formula Used
BMI = weight (kg) / height² (m²)
Where:

- weight = body weight in kilograms
- height = body height in meters (calculated from centimeters)
Example Calculation
Real-World Scenario:
A person weighing 45 kg with a height of 170 cm wants to calculate their BMI to assess if they are in a healthy weight range.
Given:
- Weight = 45 kg
- Height = 170 cm (1.7 m)
Calculation:
BMI = 45 / (1.7 × 1.7) = 45 / 2.89 = 15.57
Result: BMI of 15.57 falls into the "Severe underweight" category, which is considered medically significant and may indicate anorexia nervosa. Medical consultation is strongly recommended.
