For analog (numeric) tags that are not expression tags, you can select the engineering units for each tag to display in the chart. (Unit of measurement conversion is not supported for expression tags.)
Note: The engineering unit conversion feature is licensed separately. If you do not have
the applicable license, the button 
for unit conversion is not displayed.
To convert engineering units for tags in your chart
-
In the legend area of the chart, a button
displays beside each analog tag. Clicking the button displays a popup list of all
the related units from the engineering unit catalog for the selected tag.
-
Select an engineering unit from the list. The tag data is converted to the selected unit and the chart is refreshed.
-
You can also change multiple tags at once using the search results on the left side of the page. Search results are grouped into categories which are organized by unit of measure.
Click the
button next to the unit of measure on a search category tile.
-
Select a unit of measure from the list, and all tags from the group display in the new unit.
