On the project Options dialog box, on the Units tab, you can add project units for editing. The units defined for the project appear as optional units on editing tool dialog boxes that specify distance and direction. This enables you to enter measurements in units that are different from the map units defined by a projected coordinate system assigned to your map or scene.
For example, if your map or scene is set to a State Plane coordinate system with units in U.S. survey feet, and you add meters to the project, meter (m) appears as an optional unit in the drop-down lists on the editing tool dialog boxes. You can type the values as meters, and the tool converts the distance correctly.
To learn more about units, see the following:
- Map units, location units, and display units
- Direction formats for editing
- Distance formats for editing
