== Human Equivalent Dose Calculation based on Body Surface Area ==
Usually the correction factor (K<sub>m</sub>) is used to estimate the human equivalent does (HED) for different animal species. Km is estimated by dividing the average body weight (kg) of species to its body surface area (m²). For example, the average human body weight is 60 kg, and the body surface area is 1.62 m². Therefore, the K<sub>m</sub> factor for human is calculated by dividing 60 by 1.62, which is 37. As the K<sub>m</sub> factor for each species is constant, the K<sub>m</sub> ratio is used to simplify calculations. AED can be estimated as: AED1 (mg/kg) = AED2 (mg/kg) × Km ratio (Km2/Km1) Eq.1; or AED1 (mg/kg) = AED2 (mg/kg) × Weight2 (kg) × BSA ratio (BSA1/BSA2) Eq.2.
