 c# Syntax (Toggle Plain Text) 
using System;
 
namespace Example
{
    class FahrenheitCelsiusConverter
    {
        static void Main(string[] args)
        {
            // Get input from the user
            Console.WriteLine("Enter a temperature in Fahrenheit");
            string userInput = Console.ReadLine();
 
            // Convert user input into a number
            double fahrenheit;
            try
            {
                fahrenheit = double.Parse(userInput);
            }
            // If the user entered something that wasn't a number
            // then complain and exit
            catch (FormatException)
            {
                Console.WriteLine("Invalid input. Exiting!");
                return;
            }
 
            // Convert fahrenheit to celsius using an equation
            double celsius = (fahrenheit - 32) / 1.8;
 
            Console.WriteLine("The temperature in Celsius is " + celsius);
        }
    }
}
using System;

namespace Example
{
    class FahrenheitCelsiusConverter
    {
        static void Main(string[] args)
        {
            // Get input from the user
            Console.WriteLine("Enter a temperature in Fahrenheit");
            string userInput = Console.ReadLine();

            // Convert user input into a number
            double fahrenheit;
            try
            {
                fahrenheit = double.Parse(userInput);
            }
            // If the user entered something that wasn't a number
            // then complain and exit
            catch (FormatException)
            {
                Console.WriteLine("Invalid input. Exiting!");
                return;
            }

            // Convert fahrenheit to celsius using an equation
            double celsius = (fahrenheit - 32) / 1.8;

            Console.WriteLine("The temperature in Celsius is " + celsius);
        }
    }
}

Note that "double" is a type of number in C# that can have decimal places. If you only need whole numbers (i.e. integers), then you can use "int" instead.

ill have a go at changing the bits necessary for me
