Density Altitude Calculator
Calculates the density altitude, which represents the altitude at which the air density would be equal to the actual air density at a given location, considering temperature and pressure deviations from the standard atmosphere.
Before you use this tool
Use this if
- Calculates the density altitude, which represents the altitude at which the air density would be equal to the actual air density at a given location, considering temperature and pressure deviations from the standard atmosphere.
- You want a calculation that exposes its formula: Density Altitude = Pressure Altitude + (120 * (T - ISA Temp)) / 1000 Where: Pressure Altitude = Altitude + (29.92 - Altimeter Setting) * 1000, ISA Temp = 15 - (Pressure Altitude / 1000) * 2
- You already have Altitude, Temperature, Altimeter Setting 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.
