BSA Formulas
DuBois: BSA = 0.007184 × H^0.725 × W^0.425
Mosteller: BSA = √(H × W / 3600)
Haycock: BSA = 0.024265 × H^0.3964 × W^0.5378
Gehan-George: BSA = 0.0235 × H^0.42246 × W^0.51456

BSA is used in medicine to calculate drug doses (especially chemotherapy), cardiac index, glomerular filtration rate, and burn surface area. The average adult has a BSA of approximately 1.7 m².
