Answer 1

It looks like you program is lacking some referrence's.

You should first try to solve the error. "Program does not contain a static main"

If you solve this error, the other ones will be solved as well.

Did you make changes to program.cs ?
Can you show use program.cs ?

Also it is weird that program.cs is a "form"-file. It should be a source file with a "c#" instead.

How did you start this application ?

Answer 2

You're showing us program.cs, which you broke when you turned it into a form, or you deleted the original and named a form class file program.cs. You have 2 classes, Form1 in program.cs, and distanceConverter. The variables you are trying to reference in Program.cs don't exist there because they are declared in the distanceConverter class.
