It’s a “unit” they’re described in, I doubt they’re measured with it.

No, that’s a CSS novelty as far as I know. Especially for marketing purposes the magical “DPI” is used over here, too. But depending on device class it is (or was) common to list the dot pitch, pixel size or similar in micrometers or millimeters.
