I'm trying to calculate the area of some census tracts in qgis I go to vector -> geometry tools -> export/add geometry columns
in the resulting dialog, I calculate using project CRS. What comes out in the attribute table is something like 0.000018 or 0.0000152. I don't know what units these are in; most other information on the internet seems to say that this issue is a map projection issue.
For the record, the current map project is NAD83 EPSG 4269
I do not know what unit this is in. If I knew the unit, it would be pretty trivial to add a new 'calculating' column to the attribute table to determine the area in language I can understand.
