Thanks to the calculation above, it's quite easy to figure out a wind chill reading for temperatures between -45 degrees and 45 degrees Fahrenheit and wind speeds between 3 and 60 mph.
Here's a snapshot of my EXCEL page...
A B C
Temperature(F) | Wind Speed(mph) | Wind Chill(F) |
33 | 18 | 21.88 |
In cell C2, here's the formula as copied from the chart above:
=35.74+0.6215*A2-35.75*(B2^0.16)+0.4275*A2*(B2^0.16)
To use the NWS wind chill calculator, use the formula above or refer to the site below...
Also, review the .pdf format for the Wind Chill Chart that you see above. Something you'll notice on the chart that was not on previous charts is a frostbite indicator with exposure times.
