Alternatively, the same measurement is 752.5mm / 4 = 188.1mm, to a practical number of significant figures. No convertions between feet and inches (or ridiculous fractions of inches), and only one calculation.
Yes but my measuring tape actually has 32nds on it. The meter side only has whole divisions, not tenth graduations.
So the sae “ridiculous fraction” is a measurement I can easily make with tools I have on hand to the tools own limit of precision and double check in my head with five seconds of fifth grade level mathematics while the metric one can’t be actually measured without a set of calipers and honestly would merit long division or a calculator to double check and still needs rounding off a vile eighth of millimeter to hit what is in your own words “a practical number of significant figures”.
Imma throw something out there and I hope the earnest admission that I can’t divide 752.5 by four in my head with the level of confidence required to cut materials by is enough to recognize it not as an attack but as a real grasp at understanding:
People who make posts like yours either don’t measure things in any meaningful way (cutting, dividing, scribing lines, etc) or don’t know how to work with fractions.
Like I said: it’s not an attack, I just can’t see how someone would suggest that the metric equivalent to 13/32 is easier to work with unless they didn’t intend to actually measure it or couldn’t do fractions.
