Vensim Help

When entering units, you may want to enter the plural form as well as the singular.  For example, rabbits as well as rabbit.  This will fail a Units check because Vensim does not see the plural form as the same word.  The easiest way to accommodate this is to set rabbit and rabbits as equivalent units, or synonyms.

ØSelect menu Model>Settings... and click the Units Equiv tab.  In the editing box, type rabbit,rabbits then click the button Add Editing.  Then click OK to close the dialog.
