About BSA Formulas
Du Bois Formula
The Du Bois formula is widely used and has been validated across various populations. It uses the following equation:
BSA = 0.007184 × Weight^0.425 × Height^0.725
Where weight is in kilograms and height is in centimeters.
Mosteller Formula
The Mosteller formula is popular due to its simplicity and ease of calculation:
BSA = √(Weight × Height ÷ 3600)
This simplified formula provides accurate results and is easy to calculate mentally.
Haycock Formula
The Haycock formula was developed for use in infants, children, and adults:
BSA = 0.024265 × Weight^0.5378 × Height^0.3964
This formula is particularly useful when calculating BSA for pediatric patients.
