How BMI is Calculated
Body Mass Index (BMI) is calculated by dividing weight in kilograms by height in meters squared: BMI = kg/m². While BMI is a useful screening tool, it doesn't directly measure body fat and may not be accurate for athletes, elderly, or those with high muscle mass. Consult a healthcare provider for a complete assessment.
