Units for distance measurements using 3D objects counter

I am measuring the distance between the centers of objects using the x y and z coordinates generated by the 3D objects plugin.

For example:

Object 1: x = 7.853 y = 7.392 and z = 6.641
Object 2: x = 5 y = 9.4 and z = 5.333

Distance = 3.666

What do these coordinate mean in respect to scale? Are the xyz values pixels, and therefore I can convert pixels to units using scale bars?

Any help would be appreciated!

Hi @bfields,

I think the coordinates refer to the coordiante of the centre of the object in pixels, yes you can then convert them in units.
You can also have a look to the 3DManager that will compute distances for you :
