The workbench Geometry length unit is mm. But when I use ironPython API to get geometry Centroid, the result unit seems m and the mesh node.X seems also m.
So how to get the Centroid length unit and MeshData units ?

analysis = Model.Analyses[0]
face = analysis.GeoData.GeoEntityById(44)
faceCenter = face.Centroid 
# The Centroid unit seems m, but the workbench geometry model is mm
modelMesh = analysis.MeshData
node = modelMesh.NodeById(1)
node.X
# The node coordinate unit seems m

I am confused by the ironPython API results.
So is there any description about the units or how to get these units ?

    Thinks, if I want to get the rstfile mesh length unit. How to get it?
    I find a way but I am not sure it is right or not.

    analysis = Model.Analyses[0]
reader = analysis.GetResultsData()
rstMesh = reader.CreateMeshData()
# the rstMesh don't have unit information, try to  use local unit.
Loc = reader.GetResult('LOC')
Loc.SelectComponents(['X'])
 LocUnit = Loc.GetComponentInfo('X').Unit
# get the rstMesh node
Node = rstMesh.NodeById(NodeId)
Node.X    # get Node X  coordinate

    What's " the results file unit system specified in either the solution or solution information object in Mechanical" ?

    I forget which object it is, but one of them has a property listing the unit system of the results file.

    I found two API in solution.

    solution.ResultFileUnitSystem
#>>ConsistentNMM
solution.SolutionUnitSystem
#>>ConsistentNMM

    mm, kg, N, C, s, mV, mA
    (nmm)
