Quote 2 seems to clearly contradict quote 1. 60 is great as it divides into 2,3,4 and 5. That's a feature not a bug

And 12 divides into 2, 3, 4 and 6. Base 12 is far superior to base 10. Those Babylonians weren’t stupid.

You could call this lots of things, but you shouldn’t call it “metric” because its second is not a metric second. In the SI (metric) system, the second is one of the fundamental units. The world does not need a conflicting definition for the second. As someone who’s implemented a date and time library, the real pain is in dates, leap seconds and time zone transitions. 86,400 seconds in a day is a relative piece of ca…

You are right of course but also keep in mind that, and that is just my thoughts after reading, is that the French tried to implement decimal time along with the rest of what we call the metric system in the 18th century. And it was the only system people rejected. So I think the author named everything metric to make the point that if it would be part of the system a metric second would be … long. But again I could…

The gradian is similarly obscure, turns out 360 and 60 are nice round numbers with many handy common divisors

The problem is base 10 is a terrible base for any unit that needs to be divided. It’s an arbitrary base with no positives based on our fingers. No reasonable species would have picked base 12 when base 12 is so much better and so close. 10 can’t be evenly divided into 3 or 4 parts. 60 minutes in 3 parts is 20 minutes. 100 minutes in 3 parts is 33.3333 minutes

FTFY: English does not need a second conflicting definition for the second.

I second that statement.

> A standard hour is broken into 60 minutes. There are 2.4 standard hours in 1 metric hour.

That makes 1 metric hour equal 144 standard minutes. Since 1 metric hour is 100 metric minutes, that means 1 metric minute is 1.44 standard minutes. But the site says:

> A standard minute has 60 seconds. There are 2.4 standard minutes in 1 metric minute.

Even without doing any calculations those scale comparisons for the hour and minute can’t be the same as shown. Standard is going down by a factor of 60 and ‘metric’ by a factor of 100 so they can’t keep the same ratio.

I was going to say: time is based on degrees of a circle, and 10 doesn’t work great for it. I’m not a fan of non-metric length measurement, but time seems to be a rather sensical usage of it.

Does this short page describing a base-10 way of dividing time actually fail to be internally consistent for the few sentences of text describing it?

> A standard hour is broken into 60 minutes. There are 2.4 standard hours in 1 metric hour.

> A metric minute is broken into 100 seconds.

> A standard minute has 60 seconds. There are 2.4 standard minutes in 1 metric minute.

No, a standard minute is 1/1440 of a day, and a metric minute is 1/1000 of a day. There are 1.44 standard minutes in a metric minute.

Nothing about time is based on degrees of a circle, other than one specific way to visualise it - which many people don't use anymore and consider antiquated :)
