Does the " intensity range" mean the "Hounsfield unit" on CT dicom image?

I am trying the segmentation editor by intensity range on my CT dicom image.
Does the " intensity range" mean the “Hounsfield unit” on CT dicom image???
I compare the same dicom image on the 3D slicer and other dicom viewer. It seems the " intensity range" on 3D slicer equal to Hounsfield unit. But I am not sure about this point.

Operating system: Windows 10
Slicer version: 4.11.0
Expected behavior: segmentation by intensity range
Actual behavior:
