This program allows users to convert between Celsius, Reamur, Fahrenheit, and Kelvin temperature scales. The user selects which temperature scale they know the value in, then inputs the temperature. The program performs the necessary calculations and displays the equivalent values in the other three temperature scales. This process can be repeated by the user selecting yes to rerun the conversion program.
