What length in pixels does a Wings3D unit of measurement equate to?

[micheus]

That user @merthancioglu already did a check to for other slicers.

The default Wings3D cube 2x2x2WU has these equivalents:

Zortrax Z-Suite: 2x2x2 mm
Up pp3dp ......: 50.8x50.8x50.8 mm
Cura 4.6 ......: 2x2x2 mm
Repetier Host .: 2x2x2 mm
Chitubox ......: 2x2x2 mm
3Dwox Desktop .: 2x2x2 mm

We can see that most of them has the equivalence: 1WU = 1mm
It was a surprise the Up pp3dp.
