Wind Speed

Wind Chill Temperature:

Note: Windchill Temperature is only defined for temperatures at or below 50 degrees F and wind speeds above 3 mph. Bright sunshine may increase the wind chill temperature by 10 to 18 degrees F.

Relative Humidity Calculation

Enter in the air temperature ( Tair ) and dew point temperature ( Tdp) in degrees Fahrenheit ( oF ) then click on the Calculate RH to compute the relative humidity ( RH ).
Tair ( o F ) Tdp ( o F ) RH

Heat Index Calculation

Valid entries are, air temperatures greater than 80 F ( 27 C ), dew point temperatures greater than 65 F ( 12 C ), and relative humidities higher than 40 percent.

in Celsius

Enter in the air temperature ( Tair ) and the dew point temperature ( Tdp ) in degrees Celsius, then click on the Calculate HI to compute the heat index ( HI ).

Tair in C Tdp in C RH =

in Fahrenheit

Enter in the air temperature ( Tair ) the dew point temperature ( Tdp ) in degrees Fahrenheit, then click on the Calculate HI to compute the heat index ( HI ).

Tair in F Tdp in F RH =
