How to Calculate Wind Chill

By November 26, 2007

Follow me on:

The Beaufort Wind Scale is only one side of the tale when it comes to understanding how winter temperatures can seem so darn cold! The Wind Chill Index is a simple chart which plots wind speed and temperature. Using newer technology, scientists have put together an updated (2001) wind chill chart to demonstrate the amount of heat loss from the skin of living creatures such as humans and animals. While the temperature does not change, an increased wind speed can make it feel colder (and cause greater risk of winter deaths and injuries.)

You can learn to calculate the wind chill factor in your area by downloading these free weather calculators. Available weather calculators include

  • The Wind Chill Calculator
  • Temperature Conversions - Celsius, Fahrenheit, and Kelvin
  • Heat Index Calculator
  • Air Pressure Conversions - millibars, millimeters of mercury, hecto Pascals, standard atmospheres, inches of mercury, and pounds per square inch
  • Relative Humidity Calculator
Also included is a cricket calculator! Using an easy formula, you can actually predict the outside temperature by counting cricket chirps! Read the full story on cricket thermometers or go directly to the weather calculators page.

I was trying to find out what the wind chill was in Idaho Temp was -28, they said it felt like -48, I was on a snow machine going 60 MPH up the mountain,is it different than the -48?

Thank you

Thanks for this very interesting post Rachelle…Happy New Year to you.

Making my third weather station, all home made instrustments. Beside the school varity of instrustments where can I find more advance designs on line? I’m designing an Access Data Base using my own standards for temp, humidty, pressure, cloud cover etc. is there a standard? A simple wind chill formula would be nice, try figuring out the wct=35.74+.06215T… into a access formula.

Any input will help
Thanks Rodger

1. I can’t help you on the database part, but why start from scratch? You can submit those to existing databases such as at CoCoRaHS at http://www.srh.noaa.gov/jetstream/synoptic/cocorahs_max.htm
2. When you say standards, what exactly do you mean?
3. I cannot recommend a specific place to buy more advanced weather instruments, but have you tried contacting your local NWS office? They may even have some old ones around to give out. Free is ALWAYS good.

Here is a wind chill formula
Wind Chill (F) = 35.74 + 0.6215T – 35.75(V0.16) + 0.4275T(V0.16)
(V= wind speed in mph)

using the calculation below to figure windchill at -28 and 60MPH your windchill would be -73.5F

Here’s a good approximation of the formula:

wcf ~= 36 + 5/8T – 36V^1/6 + 7/16TV^1/6

Brrr!
