Your ideas about the ares and hectares are immaculate ;-)

Actually, you have come across a bug the long-liver, it exists
in versions

  4.1 for Microsoft Windows (November 2, 2000)
  4.0 for Microsoft Windows (April 21, 1999)
  Microsoft Windows 3.0 (April 25, 1997)
  Windows 387 2.2 (April 9, 1993)

and has been fixed recently.

In[1] := $Version
Out[1] = 4.2 for Microsoft Windows (June 5, 2002)

In[2] := << Miscellaneous`Units`
In[3] := Convert[Hectare, Are]

Out[3] = 100 Are
