BMI is calculated by dividing weight in kilograms by height in meters squared (kg/m²). For example, a person weighing 70 kg and 1.75 m tall has a BMI of 70 ÷ (1.75 × 1.75) = 22.9.
A normal BMI range is 18.5 to 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is obese according to WHO classification.
BMI doesn't directly measure body fat and may not accurately reflect body composition in athletes, elderly individuals, or those with high muscle mass. It's a screening tool, not a diagnostic measure. Always consult healthcare professionals for comprehensive health assessment.
