>Hi,

DPI refers to dot per inch. ImageJ does not refer internally to this concept.
Images are always calculated as absolute pixel x pixel values.
The calibration seting, though, is very similar to DPI
but the units are entrely arbitrary =user-selected
you can calibrate to micro-meters, meters, kilometers, miles, inches etc.
You only type in the scale factor, or if  you dont know the number
you can measure a structure with a known size and then use the
measurement as the feed-in into the calibrtation.

cheers
