The body surface area (BSA) is to calculate surface area of a human body.
There are many ways to calculate the body surface area. There are five formulas below show how to calculate BSA.
DuBois & DuBois Formula: bsa = 0.20247 × height (m)0.725 x weight (kg)0.425
Mosteller Formula: bsa = √height (cm) × weight (kg) /60
Haycock Formula: bsa = 0.024265 x height (cm)0.3964 x weight (kg)0.5378
Boyd Formula: bsa = 0.0003207 x height (cm)0.3 x weight (g)0.7285 - (0.0188 x log(weight))
Gehan and George Formula: bsa = 0.0235 x height (cm)0.42246 x weight (kg)0.51456
Where BSA is in m2, H is height in cm, and W is weight in kg.
