What is the unit of measurement used by the Shape_Length field in attribute tables?
The unit of measurement used by the Shape_Length field in attribute tables varies, as it is subject to the selected coordinate system. Some coordinate systems use angular units of measurement, while some use linear units of measurement. Angular units of measurement use degrees, while linear units of measurement use meters or feet. For example, the unit of measurement for Geographic Coordinate Systems is angular, while Projected Coordinate Systems use linear units of measurement. While selecting a coordinate system, the unit of measurement type is displayed. For more information on specifying a coordinate system, and selecting the unit of measurement types, refer to ArcGIS Help: Specifying a coordinate system.
