Wind Chill Calculator

Calculate wind chill, feels like temperature, frostbite risk, exposure guidance, and temperature difference from air temperature and wind speed. Use this wind chill calculator for winter weather, hiking, camping, outdoor work, livestock checks, school planning, and cold-weather safety.

Calculate Wind Chill

Wind Chill = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16.

How the wind chill calculator works

Wind chill from temperature:
The calculator converts your inputs to Fahrenheit and miles per hour, then applies the standard wind chill formula.

Frostbite risk estimate:
The calculator compares the wind chill result to common risk ranges and your planned exposure time.

Target feels like temperature:
Enter a target feels like temperature and the calculator estimates the wind speed needed to reach it.

Comparison mode:
Compare the wind chill at your main wind speed with a second wind speed to see how much colder it feels.

Why use a wind chill calculator?

A wind chill calculator helps estimate how cold it feels outside when wind removes heat from exposed skin faster than calm air.

It can be useful for winter travel, outdoor work, school bus stops, hiking, camping, farm chores, dog walking, sports events, and cold-weather planning.

What your result means

Your result shows the estimated wind chill temperature, temperature difference from actual air temperature, frostbite risk range, exposure comparison, wind speed conversions, and a target wind speed estimate when selected. These are planning estimates and should not replace official local weather alerts or safety guidance.

Wind chill formulas

Frequently asked questions

How do you calculate wind chill?

Wind chill is calculated from air temperature and wind speed. The standard formula uses Fahrenheit for temperature and miles per hour for wind speed.

When does wind chill apply?

Wind chill is typically used when the air temperature is 50°F or colder and wind speed is above 3 mph.

Does wind chill change the actual temperature?

No. Wind chill does not change the air temperature. It estimates how cold it feels on exposed skin because wind removes body heat faster.

Can wind chill cause frostbite?

Very low wind chill can increase frostbite risk, especially with exposed skin, wet clothing, strong wind, and long exposure.
