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.

    Step 1: Tell us, which software you're working with. Step 2: Convert: Either your data to a different CRS, or calculate manually.

    You should review existing Questions with !shape!.getArea() in CalculateField, then document the spatial reference of your layer and how you are calculating the reported area within the Question.

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.
