Formula and calculation method
Wind chill = 13.12 + .6215T − 11.37V^.16 + .3965TV^.16, in °C.
Applies at or below 10°C with wind at least about 4.8 km/h. Not a direct object temperature.
How to use wind chill calculator
- Set Temperature (°C). The example below uses -5.
- Set Wind (km/h). The example below uses 20.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Inputs and results explained
Wind Chill Calculator takes 2 inputs. Fill each one using the same units and conventions, then select Calculate.
- Temperature (°C): a number from -80 to 10. The worked example uses -5.
- Wind (km/h): a number from 4.8 to 250. The worked example uses 20.
The result panel reports Wind chill (°C).
Factors affecting your result
Applies at or below 10°C with wind at least about 4.8 km/h. Not a direct object temperature.
Changing temperature (°c) changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the wind chill calculator work?
Wind chill = 13.12 + .6215T − 11.37V^.16 + .3965TV^.16, in °C.
What inputs does Wind Chill Calculator need?
Enter temperature (°c), wind (km/h). Choose values that correspond to the same situation and measurement convention.
How should I interpret the wind chill calculator result?
Applies at or below 10°C with wind at least about 4.8 km/h. Not a direct object temperature.
Are my wind chill calculator inputs uploaded?
No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
