    }

    private static double CalculateCelsius(double fahrenheit)
    {
        double celsius;
        
        celsius = (fahrenheit - 32) * 5 / 9;
        
        return celsius;
    }

    private static void DisplayResult(double fahrenheit, double celsius)
    {
        Console.WriteLine(fahrenheit.ToString() + "° Fahrenheit is " +
            celsius.ToString() + "° Celsius");
    }
}

Output

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