Density Altitude Calculator

Calculate density altitude from field elevation, outside air temperature, altimeter setting, and optional dewpoint. Essential for aviation performance calculations.

How to Use Density Altitude Calculator

The Density Altitude Calculator determines the density altitude based on field elevation, outside air temperature (OAT), altimeter setting, and optional dewpoint. Density altitude affects aircraft performance — higher density altitude means reduced engine power and lift. The tool calculates pressure altitude, ISA standard temperature, and temperature deviation. Essential for pilots during pre-flight planning, especially at high-elevation airports or on hot days.

Step-by-Step Instructions

  1. Enter field elevation in feet
  2. Enter outside air temperature in °C or °F
  3. Enter current altimeter setting in inHg
  4. Optionally enter dewpoint for humidity correction
  5. Click Calculate to see density altitude
