Gimp is pixel based, units such as inches are only there for when it comes to printing. You can get round the minimum-unit-is-the-pixel by using paths, but no straightforward way just to change units from pixels.
Get one of Ofnuts plugins path-grid-0.1.py (date 2014-01-25) from http://sourceforge.net/projects/gimp-pat...s/scripts/
That goes in your User Gimp profile plug-ins folder C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\plug-ins
Might go like this:
1) Image -> Print Size to determine the horizontal and vertical resolution (ppi)
2) Filters -> Render -> Pattern -> Rectangular grid path and a bit of arithmetic the ppi resolution / 8 (for 1/8ths inch)
3) That gives a grid of paths which is not printable.
4) Always best to make a new layer for the grid, easy to fix if something goes wrong Layer -> New Layer
4) Set the FG colour to what you want
5) Use Edit -> Stroke path and a line width.
6) In the path dock turn the visibility off (the eye icon toggles)
That is about as accurate you will get using a bitmap editor.
