Good point. We don't & can't know, because it's a construct, not a natural phenomenon. However the comment referred to precision, not accuracy. A more precise clock can measure smaller values, making more accurate measurement possible. What standard those measurements are compared to is arbitrary.

I clocked over 50k by thumb in the US and Canada in the '70s and '80s (mostly the 80s). There were legions of kids doing it in the '70s, by the time I was doing it 5-10 years later, it was a recent enough phenomenon for most folks to be comfortable with, but uncommon enough that I never had to wait long for a ride--plus, I was a very fresh-faced, slim youngster, neither dirty- nor threatening-looking, despite my long hair and colorful garb. I pick kids up today whenever I have the chance, and hear tales of 3-day waits! What's the longest you've been stuck in one place?

1 in 20 humans alive today cannot solve a Rubick's cube. The world is huge and full of people who have no idea what one even is.

19th century euphemism, I guess. He didn't wear a glove.

Never did use those particular units, although I know what you meant was probably more like "first the US needs to fully adopt the metric system."
"The United States customary system (USCS or USC) developed from English units...However, the United Kingdom's system of measures was overhauled in 1824 to create the imperial system, changing the definitions of some units."
