BMI calculator

BMI (Body Mass Index) is an internationally used standard to judge if a person has normal weight or is overweight or underweight. The simple formula goes as follows: BMI = weight (in kilogram) / height2 (in meter). Adults have normal weight with a BMI ranging from 18,5 to 24,9 kg/m2, according to the World Health Organization (WHO). The BMI should merely be regarded as a rough guide, since neither body frame nor muscle and fat mass can be taken into account. Only a physician can judge professionally if your weight is too low or too high from a medical point of view.
