I'm new to autocad and I need to convert units into feet, for example 1''= 9329. I need to know how many feet 9329 is. I 'm sorry if this is a stupid question, but like I said I'm learning.

If need just the numeric conversion, you can use the tip 5679. To scale geometry, use the SCALE command.

Also you can use a lot of free applications for Windows, eg.: Converber.
