BSA calculator Formula:
Mosteller Formula: bsa = √height (cm) × weight (kg) /60
DuBois & DuBois Formula: bsa = 0.20247 × height (m)0.725 x weight (kg)0.425
Haycock Formula: bsa = 0.024265 x height (cm)0.3964 x weight (kg)0.5378
Gehan and George Formula: bsa = 0.0235 x height (cm)0.42246 x weight (kg)0.51456
Boyd Formula: bsa = 0.0003207 x height (cm)0.3 x weight (g)0.7285 - (0.0188 x log(weight))
