    When I find a wood working video on YouTube from the states it blows my mind how anyone can not just adopt metric “This is 5” 4/57 and we need to cut it to 5” 5/45 and a half” bzzzzzzz.

      I may be biased, but I think it kinda makes sense. All the fractions are really just powers of two:
      One half
      One quarter
      One eighth
      One sixteenth
      One thirtysecond
      etc.

        Oh yeah, totally makes more sense to say “it’s 3/64ths of an inch” than “it’s 2 millimeters.” Completely reasonable.

        So reasonable, in fact, that in most manufacturing that still uses imperial measurements they long ago abandoned fractions and moved to decimal inches.

        Which leads to unholy abominations such as the wood shop sending over “cut off 3/64ths” and the metal shop cutting off 0.046875".
