Body mass index (BMI) is a measure of body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in meters.
BMI is a simple and convenient way to assess your weight status. It is used for screening purposes and can help you track your progress if you are trying to lose weight. BMI was first developed in the 19th century by Adolphe Quetelet, a Belgian mathematician and astronomer.
