Changing scale on existing drawing

Hello I have a drawing in mm that I need to convert into inches to send to a printers in USA. any advice on how to do this?

Hi Suhep,
Try this:

-Type ‘units’ in the command line
-Press enter
-Choose ‘inches’ in the drop down menu
-Click Yes at the ‘Scale model?’ prompt

It should do the trick!
