Reminds me of the Mars orbiter misalignment

I had a Chinese made steel ruler like that once. Well they tricked me into buying it. Great for getting around the fishing size regulations.
Reminds me of the surveyors measure which is in 1/10's of a foot.
I just had something like this I dealt with. I had an L square with silk screened scales. It turned out that the ruler was printed with 25mm to the inch instead of 25.4mm to the inch.
I was trying to measure something and had used a different scale to estimate and was using the L square to try to get it more accurate. For the life of me, it was always off, so I thought, well maybe the square is not square, so I held it up against a framing square and it was square, but the numbers and lines didn't line up. There is was, each inch was off a little and it increased by length. So I checked the mm side and it was off as well.
I immediately pulled out the acetone and obliterated all of the markings. As a square it was fine, but ALL the markings were wrong.

 and be sure to only use that one throughout the build. "Pin It")
Hmmm - this reminds me of an old joke, however - I learned years ago when building projects to select one measuring tool (hopefully 1 foot equaled 1 foot) and be sure to only use that one throughout the build.
Years ago, A yard stick maker stated they wouldn't be making them any longer.
