Hi, Noticed this one in QGIS issues http://hub.qgis.org/issues/9414 Writer claims: "I just tried with a simple C++ wrapper around OSRImportFromProj4, and it seems OGR doesn't keep the unit for at least dm,cm,mm. It will only work for some units: such as km, ft, yd, us-ft, us-yd, etc." -Jukka Rahkonen-
