Remarks

Units is the type of esriUnits used by the DisplayTransformation. For example, the Map object stores its map units in this property and the units are based on the current coordinate system.  See IMap::MapUnits for more details.  Also, the PageLayout's Page object stores its units in this property and it uses inches by default.  See IPage::Units for more details. 

You should not change the units of your Map or Page using this property.  Instead, use the related properties mentioned above.   Although setting the Map's or Page's Units property will set its DisplayTransform Units property, the reverse is not always true.

Setting the Units property fires the ITransformEvents::UnitsUpdated event.
