wthrcalc has four different weather related calculations.
Wind chill - relative humidity - F to C, C to F - and heat index.
The Wind chill has both the old formula (named aeronautical since it was told to me that it was more for wing icing and such on air planes so it is based on 9 meters up), and the new formula (named civil for feet planted on ground)
xWeather - Tabbed interface for easy one hand navigation.
Profile manager to create, delete or rename profiles and track weather in multiple locations.
Nexrad radar and Satellite images, user configurable custom map urls.
