Since the body is a complex figure, making an accurate measurement of its surface is a considerable challenge. Body surface area (BSA) based dosing is a useful way to mitigate patient size variation in medication regimens. {\displaystyle \varepsilon } is the emissivity of the grey body; if it is a perfect blackbody, {\displaystyle \varepsilon =1}. In all surface area calculations, make sure that all lengths are measured in the same unit, e.g. To address it, scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body. The patient's body surface area can be estimated in several ways: by nomogram using height and weight (most accurate), by Mosteller's formula using height and weight or on the basis of weight alone (least accurate).
