Body Surface Area
Formula
BSA(m2) =
Dubois and Dubois : = 0.20247 x height (m) 0.725 x weight (kg) 0.425
Haycock : = 0.024265 x height (cm) 0.3964 x weight (kg) 0.5378
Gehan & George : = 0.0235 x height (cm) 0.42246 x weight (kg) 0.51456
Boyd : = 0.0003207 x height (cm) 0.3 x weight (kg) 0.7285 - (0.0188 x log(weight))
Mosteller: =square root (( height (cm) x weight (kg))/ 3600)
