Air Pressure at Altitude Calculator

Air Pressure at Altitude Calculator

Calculate the air pressure \(P\) at a given altitude using: $$ P = P_0 \left(1 – \frac{L\, h}{T_0}\right)^{\frac{g\, M}{R\, L}} $$

* Use SI units: altitude in meters, pressure in Pascals.

Step 1: Enter Altitude

e.g., 1000 m

Standard Parameters:
\(P_0 = 101325 \, \text{Pa}\), \(T_0 = 288.15 \, \text{K}\), \(L = 0.0065 \, \text{K/m}\), \(g = 9.80665 \, \text{m/s}^2\), \(M = 0.0289644 \, \text{kg/mol}\), \(R = 8.3144598 \, \text{J/(mol·K)}\)

Formula: $$ P = P_0 \left(1 – \frac{L\, h}{T_0}\right)^{\frac{g\, M}{R\, L}} $$
