Wind chill calculator

Wind chill is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air.

 

Actual temperature oC

  2 -1 -3 -6 -9 -12 -15

Wind speed km/h

Apparent temperature oC
0 2 -1 -3 -6 -9 -12 -15
8 -1 -3 -6 -9 -12 -15 -18
17 -6 -9 -12 -15 -18 -23 -26
25 -9 -12 -15 -18 -23 -26 -32
33 -12 -15 -18 -23 -26 -32 -34

TWC  = 13.12 + 0.6215Ta - 11.37V = 0.16 + 0.3965TaV + 0.16

Where TWC is the wind chill index, based on the Celsius temperature scale, Ta is the air temperature in degrees Celsius (C), and V is the wind speed at 10 metres (standard anemometer height), in kilometres per hour (km/h)
