Sounds like there's some kind of inch-to-millimeter conversion happening there.

Check your Tools + Options + Compatibility and the DXF options page:

What is your Unit of the File set to? Mine is set to Automatic, but Millimeter would probably work for you.

If that doesn't work, change the Unit to "Scale Factor" and "1 : 25.4" to reverse the conversion.
