Where:

• Weight — Measured in kilograms (kg)
• Height — Measured in meters (m)

Explanation: The formula calculates the ratio of weight to height squared, providing a standardized measure of body composition.

3. Importance of BMI Calculation

Details: BMI is widely used as a screening tool to identify potential weight problems in adults. It helps healthcare professionals assess health risks associated with underweight, overweight, and obesity.
