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:
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)
