In physiology and medicine, the body surface area (BSA) is the measured or
calculated surface area of a human body. For many clinical purposes BSA is a better indicator of
metabolic mass than body weight because it is less affected by abnormal adipose mass.
In this app the BSA is calculated by using the Du Bois formula: \n
BSA = (W ^ 0.425 x H ^ 0.725) x 0.007184
