Mosteller Formula for Body Surface Area
BSA (m2) = sqrt(Weight(kg) x Height(cm) / 3600)
Body surface area is used in medicine for:
Average BSA
The average adult male BSA is approximately 1.9 m2.
计算示例
A 180 lb, 70-inch tall male.
- 01Weight = 81.6 kg, Height = 177.8 cm
- 02BSA = sqrt(81.6 x 177.8 / 3600)
- 03= sqrt(14,508.48 / 3600)
- 04= sqrt(4.030) = 2.01 m2
常见问题
What is body surface area used for?
BSA is primarily used in medicine for calculating drug dosages (especially chemotherapy), determining cardiac output, and assessing burn severity.
How does BSA differ from BMI?
BMI measures weight relative to height squared and indicates weight status. BSA measures actual skin surface area and is used for physiological calculations.
What is the Mosteller formula?
The Mosteller formula (1987) is the simplest and most widely used BSA formula. It uses the square root of the product of weight and height divided by 3600.
