BMI Formula: BMI = Weight (kg) ÷ Height (m)² = Weight (kg) ÷ (Height (cm) ÷ 100)²

Example: For a person weighing 70 kg and 175 cm tall: BMI = 70 ÷ (1.75)² = 22.9 (Normal weight)

Note: BMI is a screening tool, not a diagnostic of body fatness or health. Consult a healthcare provider for a complete health assessment.
