Questions about unit scale in Unreal

I have some questions about the scale of imported meshes. The two cubes next to the arms were created at 100 units scale in XSI and from what it looks like they seem to match 1 meter of size in Unreal. Are the engine’s default humanoid skeletons modeled to a metric scale? As in, the default skeleton being about 1.8m tall? Therefore one unit in xsi would equal one centimeter in Unreal without rescaling?

UE4 uses a 1 unit = 1 cm scale.
And AFAIK everything is done in Metric.


Thanks that clears it up.
