Scaling a paperspace window in Autocad

[L i am]

Hi, I know this is a sketchup forum but I have an autocad question and I do not belong to an Autocad forum. And I am sure there are many Autocad users here.
I do not have an option for 1:250 in autocad standard scale, so I used: 1 divided by 250=0.004. So I set 0.004 in the custom scale dialogue box. Its been a long day and my brain is fried. Could somebody please confirm that a custom scale of:0.004 is 1:250?

Thanks

Sorry that I just noticed your post now.
I’m not in front of my PC at the moment, but that sounds correct.
The command line commands were...
Zoom
1/250XP
... then right-click on the viewport border to lock it.
