Change the default unit of measure

You can set the default unit of measure (for example, inches or points) that Microsoft Word uses for measurements you enter in dialog boxes and for the Word rulers.

1. On the Tools menu, click Options, and then click the General tab.
2. In the Measurement units box, click the option you want.

Note   To change the default unit of measure in dialog boxes to pixels, select the Show pixels for HTML features check box.
