What I find funny here, is not the measuring system used, but the absurd level of precision some of you wankers use.
I have seen things like “BPEL 6.549 MEG 5.137”
This cracks me up. Your measuring your cahk, not a machined stainless steel rod. Anything more than 1 digit to the right of the decimal point is assuming a level of precision you can’t possibly know. I suspect than when I see such a ridiculous claim it is because someone punched a metric measurement into their computer and it spit out a standard calculation to that level of precision.
This probably doesn’t bother your average poster, but we engineer types are annoyed by it. I can see maybe going to the hundredth place if you want to say your dick is 6 3/4 and you list it as 6.75. But please, don’t put 6.73 or worse yet, 6.739.
