How to write working code for a unit converter in Visual Basic...?

I am creating a unit converter in Visual Basic and cannot get my code to work. I need to define my variables and insert the proper math to convert feet to meters, gallons to liters, etc. The user is supposed to put the number into an input box and then the answer should appear in the output box. Any basic help is appreciated.How to write working code for a unit converter in Visual Basic...?
