How is wind chill calculated?

Erica's Answer:

But it gets very complicated from there! The most accurate equations for heat index and wind chill also take into account the size and shape of an average person, and the amount of heat a person gives off naturally. So, the "true" wind chill equation looks like this:

Wind chill temperature = 35.74 + 0.6215T - 35.75V (**0.16) + 0.4275TV(**0.16)

In this equation, T is temperature of the air, V is velocity (wind speed), and the ** means "to the power of". It's simple algebra, but a very complicated-looking equation!
