Atmospheric Pressure at Altitude Calculator
Calculates the atmospheric pressure at a given altitude based on the barometric formula.
Before you use this tool
Use this if
- Calculates the atmospheric pressure at a given altitude based on the barometric formula.
- You want a calculation that exposes its formula: P = P₀ * exp((-g * M * h) / (R * T)) Where: P = Pressure at altitude, P₀ = Sea level pressure, g = Gravitational acceleration, M = Molar mass of air, h = Altitude, R = Gas constant, T = Temperature at altitude
- You already have Altitude, Sea Level Pressure values to enter.
Skip this if
- You need an official emergency alert or life-safety instruction.
- You need a certified professional forecast instead of a calculator estimate.
