WeatherVirtual Temperature Calculator

This calculator/converter requires the use of JavaScript enabled and capable browsers.
This calculator is designed to give the virtual temperature of a parcel of air. Virtual temperature
is a fictitious temperature that takes into account moisture in the air. The meteorologists' definition
of virtual temperature is the temperature that dry air would have if its pressure and specific volume
were equal to those of a given sample of moist air. Virtual temperature correction allows meteorologists
to use the same temperature equation for dry air even though moisture is present. The virtual temperature
is a calculated (as opposed to measured) value based on the air temperature and the determined water
content of the air. The virtual temperature is the temperature of dry air that would have the same
density and pressure as the moist air. The term station is the designation for the vertical point that
you take your measurements; vertical meaning above (or below) sea level. The absolute air pressure is
the calculated air pressure, but not corrected for altitude. It is also called the station pressure in
weather reports from NOAA. Here is the current
NOAA aviation weather.
In our calculator, enter the temperature, station pressure (absolute), and dewpoint; be sure to click on
the proper designation if using measurements other than standard in the United States. Click on Calculate
and the virtual temperature in the three scales used in Meteorology will be returned. Rankine and Réaumur
can be calculated if you wish, using our
Celsius, Fahrenheit, Kelvin, Réaumur, and Rankine temperature conversion page.
