Where the confusion for the OP possibly arises is the use of Web Mercator at various zoom levels where tiles are usually set to be 256x256 pixels and a given zoom level has a certain nominal ground resolution, so some web mapping applications use screen pixels as a means of calculating distance. The EPSG code represents the combination of the ellipsoid and the datum, so once you know it, you do not need to worry about the rest, it fully defines the horizontal coordinates system (including its unit). By default, QGIS will attempt to use the most accurate transformation available. Conversions between WKT and PROJ strings will in most cases cause a loss of information, potentially leading to erroneous transformations. PTIJ Should we be afraid of Artificial Intelligence?
