    Temperature

    // This program asks the user for a Fahrenheit temperature, 
    // converts the given temperature to Celsius,
    // and displays the results.

                celsius.ToString() + "° Celsius");
        }
    }
    

    Output

    Enter Fahrenheit temperature:
     100
    100° Fahrenheit is 37.7777777777778° Celsius
