Air density is affected by the air pressure, temperature and humidity. The
density of the air is reduced by decreased air pressure, increased temperatures
and increased moisture. A reduction in air density
reduces the engine horsepower, reduces aerodynamic lift and reduces drag.
Density altitude is defined as the pressure altitude corrected for the effects of temperature and humidity.
To use the calculator, just enter the altitude, temperature, altimeter setting and
dew-point. Then click the calculate button.

Example: at 5050 feet altitude, 95 deg F air temp, 29.45 inches-Hg altimeter setting and a dew point of 67 deg F, the Density Altitude is 9257 feet.
