Description:
Converts degrees Fahrenheit to Degrees Kelvin. Note that the Kelvin temperature scale has an absolute zero (negative Kelvin temperatures do not exist). If a temperature below -459.67 Fahrenheit (absolute 0) is passed, the funciton returns -1.

Return Values:
Returns a float.

Example:

<CFSET f=212>
<CFOUTPUT>
Given f=#f#<BR>
#f# degrees Fahrenheit = #FahrenheitToKelvin(f)# degrees Kelvin.
</CFOUTPUT>
