User Defined Function for Wind Chill
I know the formula is the same one as on the NOAA web site, but it
needs a 'threshold' to be applicable. To see why, just set the wind
speed to zero.
The NOAA web site implies -- but doesn't explicitly state that it is
valid for V = 3. See
http://www.erh.noaa.gov/er/iln/tables.htm

I got the formula off the internet.
The formula you are using is the old definition. A few years ago it was
"updated" to :
= 35.74 + 0.6215*Temp - 35.75*Wind ^0.16 + 0.4275*Temp*Wind^0.16
for °F
For °C I just apply the conversion to the °F result.
