Density Altitude Calculator
Calculate density altitude from field elevation, altimeter setting, temperature, and dewpoint. Essential for takeoff and landing performance planning.
Inputs
ft
Sea level to ~14,000 ft for US airports

How to Use This Calculator
- Enter your airport's field elevation (from sectional chart or airport directory).
- Enter the current altimeter setting from ATIS or METAR.
- Enter the outside air temperature (OAT) in Celsius.
- Optionally enter the dewpoint for humidity correction.
- Use the density altitude result to look up performance in your POH/AFM.
