是什么 Body Surface Area Calculator?

▾

Body Surface Area (BSA) is used in medicine to calculate drug doses, burn area, and cardiac output. The Mosteller formula is the most widely used due to its simplicity.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

公式

▾

f(x)Mosteller: BSA (m²) = √(Height(cm) × Weight(kg) / 3,600); DuBois: BSA = 0.007184 × H^0.725 × W^0.425

1Mosteller: BSA (m²) = √(Height(cm) × Weight(kg) / 3,600)
2DuBois: BSA = 0.007184 × H^0.725 × W^0.425
3Boyd: accounts better for extremes of weight
4Normal adult BSA: approximately 1.7–1.9 m²

BSA by Age (Mosteller)

▾

Age	Average BSA (m²)
Newborn	0.25
1 year	0.47
5 years	0.73
10 years	1.14
Adult male	1.90
Adult female	1.60

常见问题

▾

Why is BSA used instead of weight for drug dosing?

BSA correlates better with physiological processes (metabolic rate, organ function) than weight alone.

What's the normal adult BSA range?

Typically 1.7–1.9 m². Average adult ≈ 1.8 m². Children much smaller proportionally.

Which formula should I use?

Mosteller is simpler and preferred in most modern clinical settings. DuBois and Boyd for specific populations.
