GNOME Bugzilla – Bug 326718
In the UI, "dpi" is sometimes used for resolution instead of "ppi"

In the GIMP UI, there are some places where the value of the image resolution is mentioned. For the entries that allow to set it, the default setting is "pixels/inch". At other places, especially those that only display the value, it is labeled "dpi". It's most funny in the new image dialog, where you can set 72 ppi only to have them displayed as 72 ppi directly above... The image properties dialog is another place where this happens. DPI are something completely different from PPI and only makes sens when printing an image. In print, a pixel (which by itself is a somehow inaccurate term there) is composed of several dots, e.g. 16x16. GIMP shouldn't add to the confusion that is already spread over the whole world and use the unit "ppi" (or pixel per <otherunit>, respectively).
DPI is what's commonly used. While PPI would be technically more accurate, it is rather uncommon. I don't think we should do the change you suggested and vote for closing as WONTFIX. The issue should probably be raised on the mailing-lists if further discussion is needed.
Reopening after discussion on the LGM. Let's have a look at all occurences then and correct them.
2006-04-05 Sven Neumann <sven@gimp.org> * app/dialogs/preferences-dialog.c * app/widgets/gimpimagepropview.c * app/widgets/gimpsizebox.c * app/widgets/gimptemplateeditor.c: replaced "dpi" with "ppi" (bug #326718).
