C# Console Calculator No overload for method take 0 arguement

I have no idea how to use methods in my calculator app. What's wrong with my method? I write this 4 Calculator separately but have no idea ho to use methods to combine it together.

This Calculator will permit the user to choose from the following main menu:

  1. Length calculator
  2. Body Mass Index calculator
  3. Waist to Height calculator
  4. Fuel Consumption calculator
  5. Exit the calculator

My current code has 4 errors said that:

No overload for method 'BMICalculator' takes 0 arguments
No overload for method 'FuelConsumptionCalculator' takes 0 arguments
No overload for method 'LengthCalculator' takes 0 arguments No overload for method 'WaistToHeightCalculator' takes 0 argument

What am i missing??

My Current Code:

        static void LengthCalculator(string[] args) {

        double Centimetres = 0.0, Feet = 0.0, Inches = 0.0;
        string AnotherConversion = null;
        string LengthCalculatorMenu;
        int LengthCalculatorOption;

        do {
            LengthCalculatorMenu = ("Enter 1) Convert centimetres to feet and inches:"
                                 + "\nEnter 2) Convert feet and inches to centimetres:");
            Console.Write(LengthCalculatorMenu);
            LengthCalculatorOption = int.Parse(Console.ReadLine());

            if (LengthCalculatorOption == 1) {
                Console.WriteLine("Please Enter the Centimetres(cm) that you wish to convert to feet and inches");
                Centimetres = double.Parse(Console.ReadLine());
                Feet = (Centimetres / 2.54) / 12;
                int iFeet = (int)Feet;
                Inches = (Feet - (double)iFeet) * 12;

Your function is defined as 

static void WaistToHeightCalculator(string[] args)

you are calling it like this 

WaistToHeightCalculator();

you need to call it like this 

WaistToHeightCalculator(args);

You must pass all arguments that a function is defined to take. I am assuming you wrote each one of these as main and then tried to pull them all together. The error No overload for method 'BMICalculator' takes 0 arguments simply means the complier could not find a version of that function that takes no arguments. It know only of the version with one argument which is an array of strings.

edit

As @jdpenix says you also don't use args in any of the functions so you could change the functions definitions to static void WaistToHeightCalculator() and continue calling them the way you are.
