We've had this long furling tape from Japan for the longest time, for years!! thinking it was in inches. Causing us lots of mistakes and fuck ups, the whole time we thought it was our own miscalculations, that we must have messed up in converting it to metric or something.1) The unit on the tape is in tenth of a foot.2) That's almost exactly 3cm, BUT NOT QUITE.3) The ruler says FEET, but then breaks it down in 3cm segments each divided in tenth of a tenth of foot.WHAT THE FUCK RULER

@alderwick here I was hating on the fact that the word "hexadecimal" mixes up latin and greek roots.

@neauoire shaku-sun-bu approximator based on international feet, I guess? unless zhat's slightly off and actually 0.9942x ze measurement on your tri-blade ruler, which'd mean it's literally just shaku-sun-bu

@yaodema it's a german triblade, so I think that's probably actual feet. If not, our measurements have been fucked on meta levels.

@neauoire oh I mean your tri-blade being *actual feet* and zhis weird ruler being off by a tiny amount you can't see wizhout calipers, here. shaku are defined as 30.3cm to a foot's 30.48, after all

We kindda wanna pass it on, but we'll have to put a label on it something, like: CURSED UNITS, experimental uses only.

@neauoire isn’t that just a standard drafting scale, at 1:10000 feet? We used the metric ones in school, but they were standard scales.

it's not just in oilfields. surveyors use decimal feet (and decimal "US survey feet" which are different) and that's almost certainly a surveyor's tape.decimal feet used to be somewhat common in all kinds of engineering, but it seems to have stuck around longest in civil engineering.CC: @neauoire@merveilles.town

@neauoire So, wait—when it hits 10, does it go back to 0 and count up in tenths of a foot until it gets to 2 feet? As in there are no 11 and 12 marked on there?Wow, just found one that does both:

@neauoire In forestry management we use imperial tape measures divided into 10 instead of 12. Specifically when measuring the diameter of a tree trunk. It means the result is a straight decimal, ie. 3.4' or 3.9' instead of 3'-4 4/5" or 3'-10 13/16".I mean, yeah, metric would be easier all around, but at least this method does make tabulating and synthesising results in spreadsheets easier for Americans when it's in tenths of a foot vs twelfths.

@neauoire And you should see the back side of that same measuring tape - it measures "inches", but each "inch" is in actually 3.14159 (pi π) inches long, so that you don't have to do math in the field to convert circumference to diameter!Super handy for those who know. Flabbergasting to those who don't.

@neauoire It's engineering units. I have an old folding rule, inches on one side and tenths on the other. It can be confusing. Anyhow, if you were working off plans with measurements in tenths, it is easier to use this kind of tape than converting numbers on site.

@tezoatlipoca @ori @neauoire 1/1000th of an inch is also sometimes called a "mil" which is a smidge confusing if you're used to a "millimeter" being called a "mil".1/10000th of an inch is sometimes called a "tenth".Also there's an angular unit called a "milliradian" which is 1/1000th of a radian and is also called a "mil".

@neauoire @niels Ever since learning about the short ton (https://en.wikipedia.org/wiki/Short_ton, 907kg, in the US apparently often called just the ton) I wish we defined a “long yard”, equal to 1m, and call it just “yard” in Europe for convenience.
