It is probably not worth the trouble to debate about which formula may or may not be slightly better. The normogram chart is used to determine the patients body surface area based on the height and weight. Body surface area represents the total surface of the human body and its determination has several applications in medicine such as IV fluid measurements and drug dosage. There are three types of charge densities depending upon the surface which may be one, two, or three-dimensional. Most drugs in children are dosed according to body weight (mg/kg) or body surface area (BSA) (mg/m2). Body surface area is used to obtain the most accurate medication dosage on a patient based on the square meters of body surface area. The patients size is determined as body surface area in metre square. Given were a US-based magazine, we use Imperial measurements. 1987; 317:1098.
