Has anyone ever seen a tape measure with shorter inches? I remember Dave talking about is some time ago.
-
They are called centimeters ;)
-
I don't know about shorter inches, but there is an "engineer's rule" - each foot is split up into 10 segments instead of 12.
You've got me curious now, though.

Pattern makers have rulers that compensate for the shrinkage of various metals. A rule for steel castings would indicate 1" but would be longer than 1" to adjust the pattern for shrink.

Maybe something like this?

You might look in the advertisements found in the back of "mens magazines"....

I have seen a tape measure printed on elastic so that you could stretch it to fit.

U.S. surveyor’s inch would be slightly longer by 2ppm :-/O
All REAL americans should use surveyor’s inch instead of sosialistic-communist based modern inch :-DD
-
hmm, so my board would have to be 500 inches long before i was effected by 1 thou difference, somehow i fail to see apart from things like 100's of miles in distance why the 2 standards?
I mean you already have Australians using thou, and now you want us using US surveyor's thou, stuff it, i'm going back to decimeters

I remember reading a while ago about a batch of Chinese knock-off tape measures where either the feet were sub divided into 10 'inches' or the 'feet' were only 10 real inches long, I can't remember which way round it was.

Yes, when the US finally went really metric in 1959 (without telling anyone), they changed the definition of the inch to exactly 2.54 cm, instead of the old definition of the meter as 39.37 inches, resulting in the "US Survey Foot" that followed the old definition. Otherwise, we would have had to change every single land-tenure document (deed) in the entire country, which didn't seem worth the trouble.
