Calculated with the U.S. National Weather Service / Environment Canada wind chill formula (2001). Frostbite times are approximate for healthy adults.

Wind chill is how cold it feels on exposed skin when wind carries body heat away. Enter the air temperature and wind speed to see the wind chill and how quickly frostbite can occur.

How to use the Wind Chill Calculator

  1. Enter the air temperature (°F or °C).
  2. Enter the wind speed in mph or km/h.
  3. Read the wind chill and the frostbite risk.

How it works

The calculator uses the 2001 wind chill formula adopted by the U.S. National Weather Service and Environment Canada:

WC = 35.74 + 0.6215T − 35.75V0.16 + 0.4275TV0.16

where T is air temperature in °F and V is wind speed in mph at 10 m. Wind chill is only defined at or below 50 °F (10 °C) with winds above 3 mph (4.8 km/h).

Frequently asked questions

What wind chill causes frostbite?

At a wind chill of about −28 °C (−18 °F) exposed skin can freeze in 10–30 minutes; at −40 °C (−40 °F) in 5–10 minutes.

Does wind chill affect objects or cars?

No. Wind chill describes heat loss from skin. Objects cool faster in wind but never drop below the actual air temperature.

What is the wind chill at 0 °F with 15 mph wind?

About -19 °F.
