Body Surface Area Calculator (BSA - for medication dosing)
About BSA
Body Surface Area (BSA) is used to calculate medication dosages, especially for chemotherapy and other potent drugs. It provides a more accurate dosing method than weight alone.
Mosteller is recommended by most medical institutions
BSA Formulas
Mosteller Formula (Recommended):
BSA (m²) = √((Height in cm × Weight in kg) / 3600)
DuBois Formula:
BSA (m²) = 0.007184 × (Height in cm)^0.725 × (Weight in kg)^0.425
Conversions: Height in cm = Height in inches × 2.54 | Weight in kg = Weight in lbs / 2.205
⚠️ BSA calculations are used by healthcare professionals for medication dosing. Always consult with your doctor or pharmacist.
