As a child, I would check the weather during the winter months to see if the wind chill would result in a day off school. In 2001, the National Weather Service changed the formula for calculating the wind chill.
Wind Chill calculates both the old formula and new formula wind chill temperatures. All you have to do is enter the current air temperature and the wind speed and when you hit calculate, you get the old and new formula wind chills. No graphics to take up memory, just simple data entry and a quick calculation.
Wind Chill Lite is ad supported. If you want an ad-free version, enter Wind Chill in the iTunes search window.
