Calculadora de Presión Atmosférica por Altitud — Fórmula
## Barometric Pressure at Altitude
For an isothermal atmosphere the pressure decreases exponentially with height.
### Formula
**P(h) = P0 * exp(-h / H)**
- *P0* = surface pressure
- *h* = altitude above the surface
- *H* = scale height (about 8.5 km for Earth)
Every scale height of ascent reduces the pressure by a factor of e (about 2.718).

Ejemplo Resuelto
Earth at 5 000 m altitude (P0 = 101 325 Pa, H = 8 500 m).
- P = P0 * exp(-h/H)
- P = 101325 * exp(-5000/8500)
- exp(-0.5882) = 0.5556
- P = 101325 * 0.5556 = 56 300 Pa = 0.556 atm
