To change the display units of any EUM Item Type, you must close all open documents and then select “Options”--> “Edit unit base groups...” from the File pull down menu under ‘Options’.
When you select this menu item, the Unit Base Group Editing dialog appears. By default all of the data units for each active module are displayed. For a clearer overview of the item types, close all of the model engines that are not relevant.
To change a unit select the data item that you want to change the units of. Then select the new units from the combo box list of available units.
After you have changed the data units, click ’Save and Close’. This saves your changes to the default Unit Base Groups file (EUM.ubg).
Note: If you have already added data to your model, changing the Unit Base Group will not convert any of your data. This process simply changes the displayed units in the user interface and the conversion factors used to make the input files internally consistent.
In some cases the relevant data item name is not clear, as there may be several data items with similar names. This is more likely to occur if several modules are selected at the same time. To find out which data item is correct, close the dialog and re-open your model. Then either move the mouse to the relevant text box, where a fly-over text box should appear telling you what is the relevant item type for this field. Alternatively, for gridded data, you can use the Create button to create a data file and then notice the item type that is displayed in the dialog.
Finally, occasionally, you may find that the data unit that you are looking for is not available. In this case, contact your local Technical Support Centre, who should forward your request to the developer for inclusion in the next release.
