OVERVIEW

• The following application is used calculate the degrees Celsius from a data entry in Fahrenheit degrees.
• The product is quite useful for the international traveler who needs comparable weather information when traveling to the United States from overseas.
• This product can be viewed within R Studio or an external web browser.
• View the application at the following link: linked phrase

INSTRUCTIONS FOR USE

• The temperature conversion app is easy to use.
• The right hand panel is an input window to select a temperature in Fahrenheit degrees.The scale of this runs from minus 25 degrees Fahrenheit to 100 degrees Fahrenheit. The default range can be adjusted to local weather conditions.
• The interactive code automatically updates and provides the precise conversion to Celsius.
• The code engine uses the accepted formula \( (F-32)*(5/9)=C \)
