Mixing Ratio

by Tim Brice and Todd Hall
 
 
Enter a temperature and a pressure or a dewpoint and a pressure or both a temperature and a dewpoint and a pressure:
Mixing Ratio
If you want the saturated mixing ratio enter the air temperature:  saturated mixing ratio:
Fahrenheit Celsius Kelvin grams per kilogram
If you want the actual mixing ratio enter the dewpoint:  actual mixing ratio:
Fahrenheit Celsius Kelvin grams per kilogram
Enter your actual station pressure (not the altimeter setting):  relative humidity - requires both temp and dewpoint
in of mercury mm of mercury millibars (hPA) %
If you enter both a temperature and dewpoint you'll get a bonus answer.
