N Scale Convertion Factor

I am new to the world of n scale model railroading. I had an HO set-up growing up, but didn’t get terribly detailed. I am wondering what the scale factor is for real feet and inches to “n scale”. Is there a number that I can multiply real dimensions by to get scale dimensions?

Appreciate the help

The magic number is 160.

Metro nailed it. I just wanted to say welcome to the forum and to N scale!
