Projected uses meters
Not exactly- it depends on the units used in the projection. UTM are typically meters: StatePlane in the U.S are typically feet.
While this is an older post, something that people often forget is when adding XY Longitude Latitude pairs is they need to add a - (minus) to the the longitude value when the data is in the western hemisphere. (Let's not forget the G [eography] in GIS...)
That should just about do it....
