New to Inkscape and I just noticed that I can change the grid units. But can I also change the ruler units, If so, how?

Click on the File menu, then go down to Document Properties. On first tab (called Page) you can set the default unit there and that'll change the ruler measurements.

  • this doesn't affect the measure tool units; it always seems to use mm

There are bugs with Inkscape's ruler handling. The dimensions on the ruler will not change in some cases (related to the viewbox).

Start with a new file (rather than opening an old file), and then copy and paste your objects into the new file.

See the Ruler units not saved bug.
