Converting measurements between different units can sometimes be a daunting task, especially in software like AutoCAD. However, converting millimeters (mm) to inches in AutoCAD is quite straightforward once you understand the process. In this tutorial, we will walk you through the steps to convert mm to inches in AutoCAD.

Step 1: Understand the Conversion Factor

Before we dive into the actual conversion process, it’s essential to understand the conversion factor between millimeters and inches. The conversion factor is 25.4, which means that there are 25.4 millimeters in one inch.

Step 2: Convert mm to Inches

To convert a measurement from millimeters to inches in AutoCAD, follow these simple steps:

  1. Select the measurement: Start by selecting the dimension or object that you want to convert from millimeters to inches.
  2. Open Properties Palette: Once you have selected the object, open the Properties palette by typing ‘PROPERTIES’ in the command line or by right-clicking and selecting ‘Properties’ from the context menu.
  3. Change Units: In the Properties palette, locate the ‘Unit format’ section and click on it. From the drop-down menu, select ‘Architectural’ or ‘Decimal,’ depending on your preference.
