> The wind chill calculator estimates how cold it feels on exposed skin from air temperature and wind speed, using the 2001 North American wind chill formula. It applies for temperatures at or below 10 °C and winds above 4.8 km/h.

## Inputs

- Air temperature (°C, °F, K)
- Wind speed (km/h, mph, m/s)

## Results

- Wind chill

## Formula

```
WC = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T·V^0.16   (T °C, V km/h)
```

## Explanation

Wind removes the thin layer of warm air around your skin, so you lose heat faster and feel colder.

### How to use the Wind Chill Calculator

- **Air temperature**
- **Wind speed**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

The formula combines temperature and wind speed measured at 10 m height.

### Inputs explained

FieldWhat to enterAir temperatureUnits: °C, °F, KWind speedUnits: km/h, mph, m/s

### Example values

How the main result changes when **Air temperature** changes and everything else stays at the example values above:

Air temperature (°C)Wind chill (°C)-2.5-9.7-3.75-11.4-5-13-6.25-14.6-7.5-16.3-10-19.5

## Worked example

Inputs — Air temperature: -5 °C; Wind speed: 30 km/h.

Results — **Wind chill = -13 °C**.

## FAQ

**Can wind chill freeze water?**
No, objects cannot cool below the actual air temperature.

**Why is wind measured at 10 m?**
It is the standard height for weather stations.

**What formula does the Wind Chill Calculator use?**
WC = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T·V^0.16   (T °C, V km/h).
