Wind chill is a meaningless, made-up term used to scare old people, and here's how they make it up.
Here's the formula for figuring the wind chill factor.

The National Weather Service's new wind chill formula is:

Twc=35.74 + 0.6215Ta - 35.75V0.16 + 0.4275TaV0.16

Where Twc is the wind chill temperature, Ta is the ambient temperature and V is wind speed.
It's all a scam. A 33ºF ambient temperature and a 10 mph wind "results" in a 25ºF wind chill, yet that environment still isn't cold enough to freeze water. Ever.
