📐 Body Surface Area Calculator
Calculate your body surface area (BSA) using the Mosteller formula, commonly used for medical dosing.
The Mosteller Formula
The Mosteller formula calculates BSA as: BSA (m²) = √((height in cm × weight in kg) / 3600). It is one of the most widely used formulas in clinical practice due to its simplicity and accuracy.
Why BSA Matters
Body surface area is used in medicine to calculate drug dosages (especially chemotherapy), determine cardiac index, and assess burn severity. The average adult BSA is approximately 1.7 m².
