    what is the formula for changing O scale to N scale. If I have a drawing in O
    scale, and I measure it with a O scale ruler and it is 30 ft, can I take my N scale ruler and measure it to 30 ft.:confused:

    That is the easiest way to change the scale (no matter what scale) to any other. If it is 30 real feet long, it is also 30 O scale feet, or 30 N scale feet or whatever.

    If you need to change the scale of a drawing, you can calculate approximately how much by comparing the scales.

    Reducing O scale (1:48 ) to N (1:160), use 30% (48/160 * 100)
    Enlarging N to O, use 333% (160/48 * 100)

    And so on.

    Thanks masonjar
    I see you are from Ottawa Canada. I live 30 miles from Ottawa on the Que side (Luskville). I am in Ottawa alot, also I am a member of the Ottawa valley N-Trak club. Now I am in Florida for 3 months to get away from those cold Canadian winters. If you go to logging under willy4 you will see one of scrachbuilt models, a Lombard Tractor. I read about so many formulas that I just wanted to reasure myself.
    Thank you
