Summary: Force Word 2003’s ruler to use metric measurements.
Microsoft Word 2003, by default, uses your operating system’s default unit of measurement. If, however, you would rather the ruler use centimeters instead of inches, or vice-versa, do the following:
1. Choose “Tools” then “Options”.
2. When the “Options” multi-tabbed dialog box appears, click the “General” tab.
3. Next to the “Measurement units” pull-down, choose your desired unit of measurement, such as Inches, Centimeters, Millimeters, Points, or Picas.
4. Press “OK” to close the dialog box.
