As I am at home a lot, Just for fun, I am starting to look at modelling a railroad / railway, cool but I don't do very often maths, so I used some code to write a function to help me out.
I have been wracking my brain about a function helps me translate real world measurements into a Guage such as HO or OO - this gauge correlates with a scale for example OO 1:76
