Scale question.

[kenworth]

I know alot of you probably have seen my truck. I will admit i did not build to scale and you are possibly saying why bother now or alittle to late but here we go. I would like to know what are the measurements from a foot to 1/14 scale and so on for future builds. I geuss i should know this stuff since i took drafting in high school but i think i am really rusty i know i am laughing too.
