Body Surface Area (BSA) & Chemo Calculator
Calculate clinical BSA with major formulas (Mosteller, DuBois, etc.) and estimate chemo drug quantities.

Chemo Dosing Clinical Note
Mosteller is the clinical standard due to algebraic simplicity (BSA = √[ (H × W) / 3600 ]). However, oncologist guidelines may specify DuBois or Haycock for extremely short/tall or pediatric patients.
