I’m trying to set up an accurate cut using draftboard to make a template. Using inkscape 1.1, and drew a 1" square with a 0.1px outline, to check the burn width.
The measured size was 0.978", so that seemed reasonable, but as my micrometer is metric, I went back to the gui to check if I could make a new cut by using the onscreen ruler to adjust the size.
When I turned that on, it gave a size of my 1"test square object as 0.975in !!!
So, I went back to inkscape, and the size showed as 0.976".
Back to gui, and I used the ruler tool to set the square to 1", and re-cut.
Result 25.4mm x 25.38mm !
I say this but I grew up learning the imperial system and still have trouble converting some things to metric. Living in Canada we pretty much mix and mingle both imperial and metric which can be quite painful at times. You have to have both versions of every tool because you never know when an item your working on might have fasteners from either system. Even our grocery stores try to confuse us by showing the price per pound but charging us per kilo at the till. How messed up is that eh?
but seriously. I was in a machine shop for a couple of years making Hougen Manufacturing Mag Drills. so I got the calipers and micrometers back then.
I use the metric system at work in biomedical research, so I agree it is easy to work with. the conversions are the insane part. I even drive past a couple of mi/km road signs going back and forth to work.
and I do have a set of metric sockets, impact sockets, and allen wrenches so I’m not totally in the stone age. LOL
