Q) Calculate the body surface area of a person with 1.6 m height and 80 kgs weight?
Ans) We can calculate the Body Surface Area(BSA) by following two methods
1) By Mosteller formula
2) By DuBois formula:
1) Mosteller formula:
Height = 1.6 m =160 cm
Weight = 80 kg
= 1.88 m2
2) DuBois formula:
BSA (m2 ) = 0.007184 X W0.425X H0.725
= 0.007184 X 800.425X 160 0.725
= 0.007184 X 6.43 X 39.6
= 1.83 m2
Note: There are several body surface area calculators are available in the internet. This is the way to calculate the body surface area by hand.
