Frequently asked questions
Which BSA formula does this use?
The Mosteller formula: BSA (m²) = √((height in cm × weight in kg) ÷ 3600). It is widely used because it is simple and accurate.
Why is body surface area used?
BSA is used to dose many medicines (for example chemotherapy) and to index physiological values like cardiac output.
