I have generated buffers around geocoded points on a map. The shape areas for buffers are clearly different than the shape areas generated when projecting polygons (such as tracts, CDPs, or counties). For example, the shape area for a 10mi buffer is approximately 0.097. How can I convert the buffer shape areas to the same unit of measurement as these other polygons (the other polygon units seem to be in square feet)? I am using ArcGIS Pro.
I believe the "shape area" field generated by ArcGIS Pro is expressed in the same unit as the CRS. You can check the properties of the CRS by right-clicking "Map" in your "Contents" panel, opening the properties > source > coordinate systems > details.
To obtain the area of a polygon in a specific unit, you can add a new field and calculate the area with the "Calculate Geometry Attributes" tool. This tool allows you to choose the unit you want your result expressed in.
