Ten formats are ten formats only if you know which one you want. Below is what each target expects — and what the file actually carries.
STL3MF
Any slicer — PrusaSlicer, Bambu Studio, Cura, Orca. 3MF carries the unit in the file; STL does not, so the answer is millimetres.
Run „Print check“ first: a slicer must know what is inside and what is outside, and AI or scanned models usually are not closed.
FBXGLB
FBX is the usual way in; GLB works too. Our FBX records millimetres and Z-up in the file itself, so nothing has to be guessed.
Unreal counts in CENTIMETRES. We have not tested the import ourselves, so check the size of the first object you bring in.
FBXGLB
FBX or GLB. Godot reads GLB natively; Unity takes both.
Both count in metres with Y up — neither of the two things a print file carries. We have tested neither engine ourselves: check size and up-direction on the first object.
GLBFBXOBJ
GLB, FBX or OBJ. This is the one we do test: a gate opens our FBX in Blender on every change and compares the size.
Measured: a 20 × 30 × 40 mm cube opens as 0.02 × 0.03 × 0.04 m — Blender works in metres, so that is the same thing.
This is the most common reason a model arrives a thousand times too small or lying on its side. It is a property of the format, not of our export.

„In the file“ means the program can read it and does not have to assume. Where it says no, the program guesses — and different programs guess differently.
