Trying to change the drawing units in your AutoCAD drawing from Imperial (feet/inches) to Metric (millimeters/centimeters), or vice versa? There are two methods as to how this can be done. Follow any one of them and you will get the job done in two shakes of a lamb’s tail.
Using the INSERT command:
Create a blank drawing using a template that is in the target units.
At the command line, enter “INSERT”.
In the Insert dialog box, browse to the original DWG file.
Check the box to Explode.
Click OK and specify an insertion point.
Using the SCALE command:
At the command line enter “SCALE”.
At the Select Objects prompt, enter “All“, then hit Enter.
Enter “0,0” for the base point.
When prompted for scale factor, enter the appropriate scale factor for the units to be converted, based on the following:
Inches to Millimeters = 25.4
Millimeters to Inches = 0.0393701
Inches to Centimeters = 2.54
Centimeters to Inches = 0.393701
Feet to Millimeters = 304.8
Millimeters to Feet = 0.00328084
Feet to Centimeters = 30.48
Centimeters to Feet = 0.0328084
Note: For the SCALE command method, adjust the dimension text and arrowhead height in the dimension style as needed.
