Units of time are specifically chosen to have 5, 2, and 3 as factors. It doesn't look so pretty when you compare with universal fundamentals:
> 1.000692286 milliseconds – time taken for light to travel 300 km in a vacuum
> 1.000692286 milliseconds – time taken for light to travel 300 km in a vacuum
Usually people omit c because it's power can be inferred.
And then they fail to mention to students that they're just omitting the c, causing a hilarious amount of confusion, half-truths and cargo-culting on the topic of natural units...
------
Saying that the speed of light in natural units is 1 is like saying that one meter in SI units is 1.
(s, m, kg, 10) can be seen as basis vectors of a vector space. (Multiplication is "addition", power is "multiplication".) Another base of this vector space is (h, c, GeV, 10).
I suspect this is precisely the half truths and cargo cutting you're referring to. Maybe you could explain what the problem here is.
(I have checked the assertion and it is correct)
10 hour 10 second easier.
A quarter pass 7.
(Actual 12 is a human number of look from earth. Both chi-na and ... is it a copy.)
1 metric minute = 100 seconds = 1.667 Babylonian minutes
1 metric hour = 100 metric minutes = 166.7 Babylonian minutes = 2.78 Babylonian hours.
1 day = 8.61 metric hours = 1436 Babylonian minutes = 23.93 Babylonian hours.
Thoughts?
1 metric minute = 100 metric seconds
1 metric hour = 100 metric minutes
1 day = 10 metric hours.

Why is that a thing?
The first Cray computers were designed in a cylindrical shape to keep the signal wires short. [2]
Ok..the backplane was annular
Why not 4?
If you think about it, it is a bit weird but makes so much sense working in base 60. We all do it all of the time.
I think the gp just generalized a bit to much. Units of time weren't chosen for those (prime) factors. People had simply figured out long time ago that a dozen is a nice round number.
