How the wind chill calculator works

Air temperature:
Enter the outdoor air temperature.

Wind speed:
Enter the wind speed. The calculator can use mph, km/h, m/s, or knots.

Unit conversion:
The calculator converts the values to the standard wind chill formula using Fahrenheit and miles per hour.

Wind chill result:
The result estimates the feels-like temperature on exposed skin in cold, windy conditions.

Why use a wind chill calculator?

A wind chill calculator is useful for winter weather, outdoor work, school activities, sports, walking, hunting, camping, travel, and planning around cold conditions.

The actual risk can vary based on clothing, exposure time, moisture, health, age, wind gusts, and how long skin is exposed.

What your result means

Your wind chill result estimates what the air feels like when wind removes heat from exposed skin. For example, a cold day can feel much colder when wind speed increases, even though the actual air temperature has not changed.

Frequently asked questions

What is wind chill?

Wind chill is an estimate of how cold the air feels on exposed skin when wind speed is included.

Does wind chill change the actual temperature?

No. Wind chill does not lower the measured air temperature. It estimates how cold the air feels to the body.

When should I use wind chill?

Wind chill is most useful when temperatures are cold and there is noticeable wind, especially around 50°F or below.

Can I use Celsius and km/h?

Yes. Choose Celsius for temperature and kilometers per hour for wind speed. The calculator converts the values automatically.
