If I try to draw a grid in Inkscape, there are two different options:
But both of them use pixel-metric(?).
Is it possible to use other metrics (e.g. millimeter).
As a workaround, I converted pixel->millimeter, but it didn’t work.
There is always an odd scale factor in the conversion :-(.
Do you have any solution?
Sadly, menu Extensions -> Render -> Grids > Grid... does only take pixels as the measurement.
So I am pretty sure conversion is the way to do it. I find the easiest, most accurate way to do conversion calculations for Inkscape is to do it in Inkscape.
Use the rectangle tool to draw a rectangle on the canvas, then in the tools control bar for the rectangle tool, change the units to mm, and set the rectangle to the value you need (in the picture below, I set it to 5 mm square).
Now, simply change the units back to px, and the width and height should have been converted to the pixel value:
