Wind Chill Calculator
Calculate wind chill temperature from air temperature and wind speed
About this calculator
The Wind Chill Calculator determines how cold air temperature feels on exposed skin when combined with wind speed. Wind chill occurs because moving air removes heat from your body faster than still air, making the actual temperature feel significantly colder. This tool is essential for outdoor enthusiasts, workers, and anyone planning cold-weather activities to assess hypothermia and frostbite risks. Understanding wind chill helps you dress appropriately and make informed decisions about outdoor exposure time during windy, cold conditions.
How to use
Enter the actual air temperature in degrees Fahrenheit or Celsius into the temperature field. Next, input the wind speed in miles per hour or kilometers per hour. Click calculate to instantly see the wind chill temperature, which represents how cold the weather actually feels on exposed skin.
Frequently asked questions
At what temperature does wind chill become dangerous?
Wind chill becomes dangerous below -18°F (-28°C), where frostbite can occur on exposed skin within 30 minutes of exposure.
Does wind chill affect actual temperature readings?
No, wind chill only affects how cold temperature feels on skin. It doesn't change the actual air temperature measured by thermometers.
Why is wind chill only calculated in cold weather?
Wind chill formulas are designed for temperatures below 50°F (10°C) when heat loss from wind becomes significant and potentially dangerous.
