Medicine
Body Surface Area Calculator
Calculate body surface area (BSA) in m² using the Mosteller, Du Bois or Haycock formula from your weight and height. Clinicians use BSA to dose chemotherapy, normalise cardiac index and estimate burn coverage.

Medicine
BSA-Based Dosage Calculator
Compute a body-surface-area-based medication dose using the DuBois BSA formula multiplied by the per-m² dose. Standard approach for chemotherapy and a few other classes of drugs whose pharmacokinetics scale with BSA.
