About this calculator
A wind chill calculator computes the apparent temperature felt on exposed skin when wind is present. Wind accelerates heat loss from the body surface, making the air feel colder than the actual air temperature. This is called the wind chill factor or wind chill equivalent temperature.
The wind chill formula used by Environment Canada and the US National Weather Service: WC = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T × V^0.16, where T is temperature in °C and V is wind speed in km/h.
Common uses
- Check how cold outdoor conditions really feel before going outside
- Assess frostbite risk for prolonged outdoor exposure
- Plan cold-weather clothing based on wind chill
- Determine safe outdoor work or exercise conditions in winter
Frequently asked questions
At what wind chill is frostbite a risk?
Frostbite can occur within 30 minutes when wind chill is −27°C or below. At −48°C wind chill, frostbite can happen in under 10 minutes. Frostbite risk affects exposed skin, face, ears, nose, fingers, and toes, and wearing proper insulation eliminates this risk regardless of wind chill.
