Density Altitude Calculator

Density altitude is a measure used in aviation to assess the altitude at which the air density matches the density of the air at a given pressure altitude under standard atmospheric conditions. The formula to calculate density altitude (ℎ _da​) from pressure altitude (ℎ _pa​) and temperature deviation as follows:

Where:

• h _da is the density altitude (in feet or meters),
• h _pa is the pressure altitude (in feet or meters),
• $\Delta T$ is the temperature deviation from the standard temperature at the pressure altitude (in degrees Celsius or Kelvin).
