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.
