NWS Wind Chill calculator based on the current version updated in 2001. Calculate the wind chill in celsius with this online calculator.

To calculate wind chill use the equation:
Wind Chill = 13.12 + (.6215 x T) - (11.37 x V^0.16) + (.3965 x T x V^0.16)

Example: When the temperature (in Celsius) is 2 degrees, wind speed is 7 km/h, the effective wind chill is:

Wind Chill = 13.12 + (.6215 x 2) - (11.37 x 7^0.16) + (.3965 x 2 x 7^0.16)

Wind Chill = -0.08 Degrees Celsius
