A Cold Wind
Blowing
Brrr... it's cold and windy outside. How much colder is it when
the wind is blowing?
Go to the Windchill Factor calculator and find out what it is for
various temperatures.

Use this one if the coolmath one doesn't work.

Can you determine a formula that would tell you what the wind chill
temperature will be for varying wind speeds when the air temperature is
30?
