Instructions: Enter an air temperature and a station pressure, a dewpoint temperature and a station pressure, or an air temperature, a dewpoint temperature, and a station pressure.
If you want to calculate the saturated mixing ratio, enter an air temperature:
Saturated mixing ratio:
Fahrenheit Celsius Kelvin  grams per kilogram
If you want to calculate the actual mixing ratio, enter a dewpoint temperature:
Actual mixing ratio:
Fahrenheit Celsius Kelvin  grams per kilogram
Enter an actual station pressure (not the altimeter setting):
Relative humidity (requires both air temperature and dewpoint temperature):
in of mercury mm of mercury millibars (hPa)  %
