Length calculator feet and inches

Question

In my if statement (LengthCalculatorOption == 1), I want to convert, for example, 187.96cm to feet and inches, such as 6feet 2ins. How do I do that? In my current code, it shows 6.17feet and always 0ins. I have no idea why.

static void Main(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;
            Inches = (Centimetres / 2.54) - (Feet * 12);
            Centimetres = ((Feet * 12) + Inches) * 2.54;
            Console.WriteLine("\nThe equivalent in feet and inches is {0:C} ft {1:G} ins", Feet, Inches);

            Console.Write("\nWould you like to make an another conversion? \n\n(Enter Y to make an another conversion/Enter any other key to exit):");
            AnotherConversion = Console.ReadLine();
        } else if (LengthCalculatorOption == 2) {
            Console.WriteLine("Please Enter the Feet");
            Feet = double.Parse(Console.ReadLine());
            Console.WriteLine("Please Enter the Inches");
            Inches = double.Parse(Console.ReadLine());

            Centimetres = ((Feet * 12) + Inches) * 2.54;
            Console.WriteLine("\nThe equivalent in centimetres is {0:G}cm", Centimetres);

            Console.Write("\nWould you like to make an another conversion? \n\n(Enter Y to make an another conversion/Enter any other key to exit):");
            AnotherConversion = Console.ReadLine();
        } else {
            Console.WriteLine("\n\a\t Invalid Option!Option Must be 1 or 2");
        }
    } while (AnotherConversion == "y" || AnotherConversion == "Y");

Answer 1

Try this:

Feet = (Centimetres / 2.54) / 12;
int iFeet = (int)Feet;
inches = (Feet - (double)iFeet) * 12;

To elaborate a bit:

You are defining feet as a double, which means that it will be a decimal value. So since you're dividing by 12, it can become a decimal representation.

What my code does is it converts Feet to integer (which will round it to 6 in this situation). We then subtract the double version of Feet (6.17 in this situation) which equals .17 (The remainder). We multiply that by 12 to convert from .17 feet to inches

Edit

To expand based on Scott's comment, this would be a different way to go

int totalInches = (Centimetres / 2.54); // This will take a floor function of Centimetres/2.54
int Feet = (totalInches - totalInches % 12) / 12; // This will make it divisible by 12
int inches = totalInches % 12; // This will give you the remainder after you divide by 12
