How to Calculate Body Surface Area
Calculate body surface area using the Mosteller formula.
The Formula
BSA = √(height×weight/3600)The body surface area formula uses the mathematical relationship: BSA = √(height×weight/3600). Each variable in the formula represents a measurable quantity that affects the final result.
Step-by-Step Method
- 1Identify all input values needed for the body surface area calculation.
- 2Substitute your known values into the formula: BSA = √(height×weight/3600).
- 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
- 4Check that your result has the correct units and is within a reasonable range.
- 5Verify using the interactive Body Surface Area Calculator to confirm your answer.
