Has a "metric" version of time ever been proposed? Seems odd to me that we're "ok" with divisions of 12 for time but not length. I guess for science seconds are basically the only measure of time that usually matters?
I'm not sure why a metric hour didn't catch on.

It’s also historical and pretty hard to change the basic units of time.

This is probably the dumbest thing I'll type on HN. In university I just gave up trying to understand why we even needed the Avogadro constant / mole as a fundamental constant. It still confuses me. Why have a difference between molar mass and mass? Why couldn't it just be "1" and everything else change around it?
I thought it was just a ratio. Mass per mole. I admit I have never used this in my day to day life and college was 20 years ago. So maybe I am clueless.

This is massive news.

They really should cut the middle man. What surprised me reading that wiki page is that apparently the metric system was opposed in the US based on religious reasons . That is mind-boggling.
Is there any compelling reason why the US should switch to the metric system for daily use? Metric is already used universally in science and engineering, which seem to be the main fields in which consistency across countries matters. I completely agree that in physics, chemistry, engineering, medicine, etc., it is important to use standard units. But what harm is it doing in practice if in everyday life, Americans s…
Celsius is literally the same scale as Kelvin, just shifted so that 0c = water freezing.

Seconds are the metric unit of time if I understand it correctly. It doesn’t make any sense to say “kiloseconds” or something like that because days are the time that the sun is up (ish), months are roughly based on moon cycles, and years are approximately the time it takes us to go around the sun. It’s also historical and pretty hard to change the basic units of time.

Metric had time from the start. However it was work 4 days, 1 day weekend. However the loss of personal time was very unpopular so it never caught on. I'm not sure why a metric hour didn't catch on.

At least there will be no disagreement about the shipping weight on the auction listing.
The real question is how many boxes will the fulfilment center place the kg in. If Amazon is anything to go by my money is on 3
I recently ordered a picture frame from Amazon. It came in its packaging box, which was placed in a box by the manufacturer. That box was put in another box by Amazon and shrink wrapped to a large piece of cardboard, which was then put inside yet another box.
On the surface, it seems crazy, but Amazon did manage to get it to me undamaged.
