Body Mass Index (BMI) is a medical screening tool used to estimate body fat based on an individual's weight in relation to their height. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. While BMI is generally a good indicator of body fatness, it is not always accurate and should be used alongside other health assessments.

Body Mass Index is calculated by dividing weight in kilograms (kg) by height in meters (m) squared.

Calculating BMI is crucial for assessing an individual's risk of developing health conditions such as heart disease, stroke, and type-2 diabetes. It also helps identify potential issues like malnutrition if the BMI is too low. Although BMI is a useful tool, it should be used in conjunction with other health assessments for a comprehensive understanding of an individual’s health status.
