| Wind speeds above 40 mph have little additional chilling affect | |||||||||||||
If you would like to calculate the wind chill index for combinations of temperature and wind other than those given in the table above, you can use the following formula: |
||
|---|---|---|
| WC = 91.4 - (0.474677 - 0.020425 * V + 0.303107 * SQRT(V)) * (91.4 - T) | ||
| where: | WC = wind chill index V = wind speed (mph) T = temperature (° F) |
