    True that, especially as they shrinkflate it. A chocolate bar is usually 50-60g these days. Used to be 71g as I was a kid. Gee I wonder where that number came from…

    I’ve heard that one of the reasons that metrification didn’t take off in the States was that when they converted highway signs, they rounded down instead of up, so people got mad at “losing” a couple km/h. Tactical error, there.

    yeah, a duodecimal metric system would have been better. Still, it’s more important to have a standard system than it is for it to be ideal. It’s the strongest argument for US customary system within the USA, as well - but that argument breaks down when you widen the scope to the world.

    In the 18th century context, and its dozens of competing measurement systems, something like the metric system was sorely needed just for standardization. We’re just lucky that it was something more or less sensible. Had the US customary system won out, I think we’d be objectively worse off.

    So it could have been better, but it could also have been MUCH much much worse.

    In any context where it’s important, you’d note it with +/-. Not really a problem.

    I guess there’s nothing wrong with saying 1/8th metre, 1/8th centimetre, 15/16th metre either. Just as some people might use 0.356 inches.

    0.625 implies your measurement is precise to the nearest thousandth

    It does. If it were precise to less than that, you’d say 0.62 or 0.6 to indicate hundredths or tenths. Why would you say 0.625 if you’re not precise to thousandths? You’d say 0.62500 if you wanted to indicate precision to hundred-thousandths.

    “The fraction allows you to communicate length and tolerance in a single number”

    I don’t see how that isn’t true of decimals, too. 0.1 indicates a precision of 1 digit, 0.12 indicates a precision of 2, 0.120 indicates a precision of three.

    This hurts my brain. Why do we care about all the weird fractions? +/- 0.1 is just another way of saying 1/10. You can still do that if you want without having to do fraction math in random denominators.
