Calculate the feels-like temperature
Enter the temperature and wind speed: the tool applies the wind chill formula and flags frostbite risk.
Key points
- More wind = colder feel
- Valid for T ≤ 10 °C and wind ≥ 5 km/h
- Frostbite risk below −27 °C felt
- Cover exposed skin
Example
| Input | Value |
|---|---|
| Temperature | −5 °C |
| Wind | 30 km/h |
| Feels like | ≈ −13 °C |

Frequently asked questions
What is wind chill?
The wind’s effect that speeds up body heat loss: it feels “colder” than the actual temperature.
Which formula?
The Canadian/US formula: 13.12 + 0.6215·T − 11.37·v^0.16 + 0.3965·T·v^0.16 (T in °C, v in km/h).
When does it apply?
For temperature ≤ 10 °C and wind ≥ 5 km/h; outside that, the feel is close to the actual temperature.
When is it dangerous?
Below −27 °C felt, frostbite can occur within minutes: protect yourself.
