About Body Mass Index (BMI)

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.

BMI Categories

•Underweight: BMI less than 18.5
•Normal: BMI 18.5 to 24.9
•Overweight: BMI 25 to 29.9
•Obese: BMI 30 or greater

Formula

BMI = Weight (kg) / Height (m)²

Note: BMI is a screening tool, not a diagnostic of body fatness or health.

Important Considerations

BMI doesn't distinguish between muscle and fat mass
Athletes may have high BMI due to muscle mass
Not suitable for children and adolescents
