PDF scale vs Rhino Scale

If my PDF is a 1/4" = 1’ scale
what do I need to type in to rhino so that it translates it into a full scale version?
Rhino asks ___inch in PDF = ___Rhino Unit.

so basically on my pdf, 1’ looks like 1/4", and when I import it into Rhino, I want it to show up as 1’, without having to scale anything.

I think I got hit in the head… which I did, yesterday… LOL
12UNITS… HELLO!

I guess .25" in pdf = 1" in Rhino would do it. Any luck?

told it to do 1/4" in PDF to 12 Units in Rhino and it worked like a charm:)
