Wind Chill Chart And Calculator

Interactive Wind Chill Widget

Official Wind Chill is calculated using the observed sustained wind speed, not the gust.   But that peak gust will make you feel even colder.

Mathmatical Formula – How To Calculate Wind Chill

From the user, we are given an air temperature (T) and a wind speed (Windsfc). In order to calculate the Wind Chill, the temperature must be converted to degrees Fahrenheit (°F).

To find out how to convert the temperature, see the link below:

Temperature Conversion

Also, in order to calculate the Wind Chill, the wind speed must be converted to miles per hour (​mph).

To find out how to convert the wind speed, see the link below:

Wind Speed Conversion

Then, the Wind Chill can be calculated using this formula:

WindChill = 35.74 + (0.6215 × T) − (35.75 × Wind0.16) sfc + (0.4275 × T × Wind0.16) sfc

Because the user might need the Wind Chill in Watts per meter squared​ m2 ​, it can (W)  be calculated using an air temperature in degrees Celsius (°C) and a wind speed in meters per second s ​: (m)

WindChill = (12.1452 + 11.6222 × √Windsfc − 1.16222 × Windsfc) × (33 − T)
