Yeah, there seems to be a narrow margin of error that gets exponentially more noticeable. Glad to help where I can!

Im still working on some other issues inbumpedninto. I noticed when a selection consists of multiple compoundpathitems, it would return the shape count as 1. Currently working on that. I believe the calculations are now fixed. As far as I can do that. I've noticed that still sometimes it returns a none round number even when the length and with are round numbers.. the pixel area is now as close as I can get it
Cool, thanks for updating this and helping out! I appreciate all the work you've done. Will you update the code when you iron out those bumps you were talking about?
Of course I will
For some reasons, it got negative area for some paths, so for multiple paths it substracted them. not added. Fixed with adding math.abs:
var totalArea = totalArea + Math.abs(objects[i].area);
But unfortunately, now compound shape calculation doesn't work correctly ¯_(ツ)_/¯

thanks for highlighting this. It seems there is indeed and issue somewhere. I check the raw output of the area. Thats the negative number in the screengrab. Right is the number from that big white square. Which does have its awkward not rounded number 717 x x716.9996 px
I need to go over the code and see whats cause this.
Whats weird is that i checked it with lower values and it always seemed to return proper area values. like says 10x10 or 100x100
I think its an issue with using pixels and the conversion. If i use mm as ruler input and use those values of the square. I get 252.942 mm x 252.942 mm = 63979.655364 from a calculator and 63979.57105 from the script. Still not correct, but its closer
I think its due to my hot mess of using different decimals. i should look into this and make this neater code.
