Body Surface Area
Calculate body surface area with Mosteller or Du Bois and compare both results.
How to use
- Enter height in cm and weight in kg.
- Choose Mosteller or Du Bois as the primary result and calculate.
Capabilities and scope
You can choose the primary formula while the runner shows both values and their absolute difference in m².
How it works
Mosteller=√(height×weight/3600); DuBois=0.007184×height^0.725×weight^0.425.
Example
At 170 cm and 70 kg, the runner shows both BSA estimates and their small difference.
Interpretation
Height and weight must both be greater than zero.
Useful for
- Compare two common BSA equations
- Understand how a BSA value is derived from height and weight
Before you use it
- Clinical decisions such as drug dosing must use the formula specified by the relevant protocol and professional judgment.

Frequently asked questions
Is one formula always more accurate?
No. Suitability depends on context; this tool compares equations rather than choosing a clinical protocol.
