Haycock et al developed an equation for predicting body surface area of a patient based on body weight and height. The formula is similar to that of Gehan and George (above).


Population: The equation has been validated for infants, children and adults.


body surface area in square meters =

= (0.024265) * ((weight in kg)^(0.5378)) * ((height in cm)^(0.3964))
