Rhino and Grasshopper unit system compatibility

I have created a Rhino file in “m” and worked in grasshopper in “m” but now I have to create a rhino file in “Large objects-mm” but I don’ know If the reference(curve) taken in grasshopper will have units in which system(m,mm or something else).

Grasshopper will always follow Rhino’s unit setting.

Thank you Keyu!
