Air Pressure at Altitude Calculator

Estimate standard-atmosphere pressure for a given altitude

📖 Barometric Formula

Uses the International Standard Atmosphere (troposphere) lapse-rate equation P = P₀ (1 − L h / T₀)^{(g·M)/(R·L)} to estimate static pressure from geometric altitude.

📊 Result

💡 Tips & Information

  • Valid up to the top of the troposphere (~11 km).
  • Results assume a standard lapse rate of 6.5 K/km.
  • Use observed sea-level pressure for localized adjustments.
