How Do I Change Units in Feet and Inches in AutoCAD?

If you are using AutoCAD for your design projects, you may often come across situations where you need to change units from feet and inches. AutoCAD provides a simple and efficient way to make this conversion. In this tutorial, we will guide you through the steps to change units in feet and inches in AutoCAD.

Step 1: Accessing Drawing Units

To change the units in AutoCAD, you first need to access the Drawing Units dialog box. This can be done by clicking on the “Format” menu at the top of the screen, then selecting “Units” from the drop-down menu.

Step 2: Selecting the desired units

Once you have opened the Drawing Units dialog box, you will see various options for different unit types such as length, angle, area, and more. To change units specifically for feet and inches, focus on the “Length” section.

Note: By default, AutoCAD uses decimal units for length measurement. To switch to feet and inches, follow these steps:

  1. Select “Architectural” from the “Type” drop-down menu.
  2. In the “Precision” section below, choose your desired precision level for displaying fractional inches. For example, if you want to display measurements up to 1/8 inch precision, select “1/8”.
  3. Click on the “OK” button at the bottom of the dialog box to save your changes.

Note: If you prefer a different precision level or want to use a different unit type altogether (e.g., Engineering or Decimal), feel free to explore other options in this dialog box before clicking “OK”.

Step 3: Applying the changes

After you have made your desired changes in the Drawing Units dialog box, AutoCAD will apply them to the current drawing. Any new objects you create or existing objects you modify will adhere to the updated unit settings.

Note: If you have already drawn objects in your drawing before changing the units, they will not automatically convert to the new units. You may need to manually adjust their measurements using appropriate tools in AutoCAD.


In conclusion, changing units from decimal to feet and inches in AutoCAD is a straightforward process. By following the steps outlined in this tutorial, you can easily modify your unit settings and begin working with measurements that are more suitable for your specific design needs.

Remember, always double-check your unit settings before starting any new project or making critical measurements in AutoCAD to ensure accurate and consistent results.
