your issue is that else if (choice == 5) is inside else if (choice == 4)

JJimmahdean3/6/2023

else if (choice == 4)
{
    Console.WriteLine("Which unit would you like to convert from?");
    Console.WriteLine("1. Pounds");
    Console.WriteLine("2. Kilograms");

    int fromUnit = int.Parse(Console.ReadLine());

    Console.WriteLine("Which unit would you like to convert to?");
    Console.WriteLine("1. Pounds");
    Console.WriteLine("2. Kilograms");

    int toUnit = int.Parse(Console.ReadLine());

    Console.WriteLine("Enter the value to convert:");

    double value = double.Parse(Console.ReadLine());

    if (fromUnit == 1 && toUnit == 2)
    {
        value /= 2.205;
    }
    else if (choice == 5)
    {

you need to add another brace on line 138

u cant define a variable of the same name twice in the same scope

TTheRanger3/6/2023

u can atleast reassign a value to it without redefining it

TTheRanger3/6/2023

 int fromUnit = int.Parse(Console.ReadLine()); // this is declaration and assigning a value

 fromUnit = int.Parse(Console.ReadLine()); // this is only assigning a value
