How to convert from Imperial to metric

I work with Centrial American companys who have a hard time with conversion from what I can work with (imperial) to their metric. Is there an easy way to convert back and forth?

I dont know in AutoCAD, but in inventor you simply input the value and the standard.

See picture,

55 in, my input and the 1397 is what the inventor converts it to. (mm)

Probably not what you want to hear but I would learn to draw in both Metric and Imperial. Converting units is ok for approximations but when you need things to be accurate the conversions will end up with so many decimal places that your models will upset the machine shop guys or end up not fitting correctly.

Good luck

Guys, I'll try to help you. :)
In the menu bar of AutoCAD, click Format-->Units.
You can choose the unit of AutoCAD before you draw.

Okay, if you have problem about my answer, I'll guide you until you can handle it.

At the Command Line, enter STARTUP and change the value to 1. Now when opening a new starch file you will be prompt to choose what units (imperal or metric) you want to use. Open correct unit drawing file and then copy paste your drawing in.

The best way I have found is to create 2 separate templates, one in Imperial and one in Metric. Otherwise when you start-up Auto CAD a "Startup" window should pop up. When this window opens select the start from scratch icon and below default settings it gives you the option of selecting either Imperial or Metric, but as I said before it is easier to have separate templates.

When you go to create your template files make sure to save them as .DWT (template) files. To open them you will need to select Use a Template (Third button from the left in the Startup dialog box). AutoCAD defaults the search to your hard drive where AutoCAD is installed in a folder called Templates.
