mesh spatial dimension in OpenFOAM

My default mesh geometry length is in 80 mm. For OpenFoam, I scaled the mesh in meters as 0.008 m. Once I import the mesh in OpenFOAM, it is a collection of point coordinates. Now, the location of these points and spatial difference between different points will be the same either if they are in mm or m. I feel spatial unit is arbitrary here?
I want to understand when do I have to scale the geometry in Openfoam and when not?

then you will see the scale of your geometry, if it differs from what you intended then you can use transformPoints -scale '(x x x)'
where x is your scale.
