Как да изчислим Body Surface Area Calculator
Какво е Body Surface Area Calculator?
Body Surface Area (BSA) is the measured or calculated surface area of a human body. It is used in clinical medicine to calculate drug doses (particularly chemotherapy), burn area assessment, and metabolic rate estimation. BSA is considered more accurate than body weight alone for drug dosing.

- 1Mosteller formula: BSA = √(H × W / 3600) — simple and widely used
- 2DuBois formula: BSA = 0.007184 × H^0.725 × W^0.425 — original 1916 formula
- 3Haycock formula: BSA = 0.024265 × H^0.3964 × W^0.5378 — most accurate for children
- 4H = height in cm, W = weight in kg, result in m²
Worked Examples
Вход
Adult male: 80 kg, 180 cm
Резултат
BSA ≈ 2.0 m²
Average adult male BSA is 1.9 m²
Вход
Child: 20 kg, 110 cm
Резултат
BSA ≈ 0.76 m²
BSA scales non-linearly with size
