What the tool does, how to run it, and what to expect from the result.
Body surface area is used to dose chemotherapy and some other drugs, and to index cardiac output. Mosteller, the most common: BSA = √(height cm × weight kg ÷ 3600). For 175 cm and 70 kg that is √(12,250 ÷ 3600) = 1.845 m². DuBois (1916) and Haycock (used in children) give 1.848 and 1.847 m² for the same person.
