The wind chill temperature is a measure of how cold it really feels outside based on the air temperature and wind speed.

**How to use this calculator**

- Select the wind speed unit between mph, km/h, m/s, ft/s, knots
- Enter the wind speed
- Choose the temperature unit between degrees Fahrenheit, degrees Celsius, or Kelvin
- Enter the air temperature and click the "Calculate" button to estimate the wind chill temperature.

## Wind Chill Formula

The Wind Chill Calculator uses the following formulas to calculate the wind chill factor:

WC (Wind Chill,
°F) = 35.74 + 0.6215 × T - 35.75 × V^{ 0.16} + 0.4275
× T × V^{ 0.16}

*Where:*

*V is the wind speed in miles per hour (mph),*

*T is the air temperature in Fahrenheit (°F).*

**Wind (mph) = 0.621371 × Wind (km/h)**

**Wind (mph) = 2.23694 × Wind (m/s)**

**Wind (mph) = 0.681818 × Wind (ft/s)**

**Wind (mph) = 1.15077945 × Wind (kts)**

*Where:*

*Wind (mph) is the wind speed in miles per hour,*

*Wind (km/h) is the wind speed in kilometers per hour,*

*Wind (m/s) is the wind speed in meters per second,*

*Wind (ft/s) is the wind speed in feet per second,*

*Wind (kts) is the wind speed in knots.*

**T _{F} = 1.8 × T_{C} + 32**

**T _{F} = 1.8 × (T_{K} - 273.15) + 32**

**T _{C} = 0.55556 × (T_{F} - 32)**

**T _{K} = ( 0.55556 × (T_{F} - 32) ) + 273.15**

*Where:*

*T _{F} is temperature in Fahrenheit,*

*T _{C} is temperature in Celsius,*

*T _{K} is temperature in Kelvin.*

**Example:** If the outside temperature is 5°F and the
wind speed is 30 mph, the wind chill temperature is:

WC (Wind Chill, °F) = 35.74 + (.6215 × 5) - (35.75 × 30^{
0.16}) + (.4275 × 5 × 30^{ 0.16})

Wind Chill = 35.74 + (.6215 × 5) - (35.75 × 1.723) + (.4275 × 5 × 1.723)

Wind Chill = 38.847 - 61.597 + 3.683 = -19.066 degrees Fahrenheit.
