Change Ruler Units in Microsoft Word
Microsoft Word allows you to display document measurements in centimetres or inches. These units appear on the Word ruler and affect margins, tab stops, indentation, and other layout settings. If the ruler in your document is using the wrong unit system, you can change it quickly in Word’s settings.
The steps depend on whether you are using Word for Mac or Word for Windows.
