A "mil" in the US is a thousandth of an inch, not a millimeter.

Not just mix of units but fractions too. While sometimes 1/2, 1/4, 1/8 etc can lend itself to very convenient mathematical solutions (eg when doubling or halving) more often than not it doesn't.

The factors of ten aren't important. The important bit is the
reproducibility of accurate measurement.
With the exception of the kilogram, all SI units are derived from

The Yanks are really weird, a speedboat nut at work (an
Aussie) always talks about his racing speeds in mph. When
asked why not knots, "It's always been like that".
They also use mph in aircraft

distance until they developed and could operate globally and thus the
majority moved to knots & NM.
Many iconic A/C from WW2 started out with MPH ASI's and ended up later with
knots.

while we are resolving the measuring units, how about we all go to UTC instead
of working on local time. Then we wouldn't have to change all those clocks and
watches and everything else with a timepiece in it twice a year. After all it's
only a number

I think it goes a _real_ long way back, Chris.
Vague memories of the _Babylonians_ using a base 12 numbering system as the basis of their astrological/mathematical systems.

This from http://www.springfrog.com/converter/decimal-time.htm
Why are there 60 minutes in an hour and 24 hours in a day?
The fact that we have 24 hours in a day dates back to the Ancient Egyptians.
The Egyyptians actually had 10 hours during the day, and developed a sundial
around 1500 B.C wh
Both numbers have a large number of divisors, otherwise I dunno
24 can be divided by 2, 3, 4, 6, 8 and 12
360 can be divided by
2,3,4,5,6,8,9,10,12,15,18,20,24,30,36,40,45,60,72,90,180

The story I remember from school (whether true or false) was that these numbers
were chosen because they are easily divisible:
i.e. all multiples of 60 are divisible by 1,2,3,4,5,6
Once again, I'm not sure if it is true.

Trite I know, but it all relates back to somebod(ies) dividing the siderial
day into 24 hours and a circle into 360 degrees.
Would'nt it be great to have a 10 hour day with a hundred divisions
(minutes) and 1000 degrees in a circle.
Politically and economically impossible though.

Agree with Mark here. It isn't that hard.
For the reverse situation in Germany (me) flying their gliders with height in metres and ASI in kph was not really harder (nor easier!), just another "set" of numbers to use. Of course, German power pilots use f
