How to modify the units of a drawing in AutoCAD, such as from Imperial (feet/inches) to Metric (mm, cm, m), or vice versa.

Solution:

These are the main methods to convert a drawing units.

Alternative i (preferred method): Utilise -DWGUNITS

1. Enter the-DWGUNITS command. The following prompts will exist performed in succession:
   1. Cartoon units.
   2. Drawing unit brandish formats.
   3. Linear display format.
   4. Linear display precision.
   5. Scale objects from other drawings upon insert?
   6. Match INSUNITS to drawing units?
   7. Scale objects in current cartoon to reflect alter in units?
   8. Include objects in Paper Space?
2. Choose a drawing unit of measurement other than the current one on footstep 1.
3. On stride 7, and optionally step 8, chooseYes.

Note: According to the chosen options, some prompts may be skipped past pressing Enter.

See the following example of command line text ( in red what yous have to enter) In this example the drawing will be converted from inches to millimeter:

Control:                                  -DWGUNITS                                Loading AEC Base of operations... Loading AEC Base of operations Extended... Loading AEC Cadre... Drawing units:   one. Inches   two. Feet   three. Millimeters   4. Centimeters   5. Decimeters   6. Meters Unit for length <1>:                                  three                                Cartoon unit of measurement display formats:   1. Scientific   2. Decimal Linear display format <2>:                                  ii                                Linear display precision <four>:                                  <Enter to accept the proposed 4 for the linear precision>                                Calibration objects from other drawings upon insert? [Yes/No] <Yeah>:                   <Enter to to take the proposed "Yes">                                Match INSUNITS to cartoon units? [Yes/No] <Yes>:                                  <Enter to to accept the proposed "Yes">                                ** Alarm: you have changed the unit for this drawing database.  **  ** All new objects will be fatigued according to the new unit, merely   **  ** existing objects will not change size unless you specifically  **  ** enquire to have automatic scaling occur.                           ** Scale objects in electric current cartoon to reflect change in units? [Yeah/No] <Yes>: Include objects in Paper Space? [Yes/No] <Yes>:                                  <Enter to to have the proposed "Yes">                                Scaling the entire database... Scaling AecDbObject(s)... Scaling entities in Model Space... Scaling entities in Paper Infinite... Scaling entities in Paper Space...

Notes for AutoCAD Establish 3D:This control can only catechumen plain AutoCAD components like lines, arcs, ... but non all AutoCAD Plant 3D components similar AutoCAD Plant 3D elbows. Don't utilize DWGUNITS for AutoCAD Constitute 3D.

Alternative ii: Use the INSERT command

In this instance the components will exist converted from inches to feet.

1. Starting time a new drawing using the acad.dwt template.
2. Enter theUNITS command.
3. Select "Decimal" forType and "Feet" forInsertion calibration. ClickOK.
4. Enter theINSERT control (orCLASSICINSERT in AutoCAD 2020 and newer).
5. Click theBrowse push button and select the inch-based drawing.
6. Deselect all options so the drawing volition go in at 0,0, no scaling, and no rotation.
7. Select the checkbox for "Explode" and clickOK.

Alternative iii: Use the SCALE command

1. At the command line, enter SCALE.
2. At the Select objects prompt, enter All.
3. Enter 0,0 for the base of operations bespeak.
4. When prompted for scale gene, enter the advisable scale gene for the units to be converted, based on the following listing:

Scale Factors

:

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

Notes:

• For the Calibration command method, adjust the dimension text and arrowhead peak in the dimension style as needed.
• Layout viewports may demand to be moved or resized, or the plot scale updated, when an alternate unit page size is selected after conversion. For case, when an imperial paper size is selected in a drawing that has been converted to metric.
