In this project you will create an application to convert temperature readings between Fahrenheit and Celsius and between Celsius and Fahrenheit. The formula to convert a Fahrenheit temperature to the Celsius scale is

Celsius $5($Fahrenheit $232)/1\mathrm{.}8$

and the formula to convert a Celsius temperature to the Fahrenheit scale is Fahrenheit $5$ Celsius $31\mathrm{.}8132$

Users will enter a value in a Celsius or Fahrenheit input box, press the Tab key and have the other input box automatically show the temperature reading in the other scale. A preview of the completed page is shown in Figure $2-30.$
