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 tem
