Bring back the units to defaults (mm), and follow the instructions in this thread.

> Operating system: Win10 Slicer version: 5.2.1 r31317 / 77da381 Hi, I am encountering the following problem: segments were obtained by using the segment editor the voxel spacing of the master volume was: 1 x 1 x 1 mm³ (the default value) now I would need to change the voxel spacing of the master volume and also the voxel spacing of the already obtained segments Unfortunately I couldn´t find a smooth solution for this task; once the voxel dimensions of the master volume are changed, the cha…

You should of course correct the spacing in the master volume same way as well.
