The Wind Chill Index calculator computes the wind chill index based on the air temperature and the velocity of the wind.
INSTRUCTIONS: Choose units and enter the following:
Wind Chill (TWC): The calculator returns the wind chill in degrees Fahrenheit. However, this can be automatically converted to compatible units via the pull-down menu.
Theis popularly known as the . It is a calculation of the perceived decrease in temperature which is experienced when wind blows across an exposed surface.
Thein this calculator is:
TWC = 35.74 + 0.6215 • Ta - 35.75 • V0.16 + 0.4275•TA • V0.16
This equation takes as input the wind speed (MPH) and the outside ambient air temperature (F) in order to match the coefficients. These are used to computer the Wind Chill Index, which is the perceived (what it really feels like) temperature.
