The largest bitch I see with God's units over that commie shit is but 'muh factions and divisible by ten'.

Surveyors and civil types figured it out forever ago- use decimal feet.  

Best of both worlds.

We use it in excavating.  It's amazing that guys can't grasp it.

I use decimal feet. It's mildly annoying when I have to translate it to feet and inches for other people from time to time.

It's way better.  I mentioned surveyors, I suppose I should have said civil construction as a whole.

If we used base 12, it would make a whole lot more sense.  The simple reason for inches is that you can easily divide a foot by halves, thirds, quarters, and sixths.

.500, .333, .250, .167

Don't make this harder than it needs to be.

Of all places to use a fraction, probably the 2nd most notable (behind 1/3) is Pi, 22/7, and it's taught as a decimal.

But, in base twelve, 1/2 is 0.6, 1/3 is 0.4 (no repeating for ever), 1/4 is 0.3, and 1/6 is 0.2, etc.  It does simplify common fractions.  The only better base (but more cumbersome) is base 24 to reduce repeating decimals for common fractions.

Also, pi is not a fraction. It is the ratio of the circumference of a circle to its diameter.  It is irrational, meaning there is no expressible ratio in numerical form.  The fraction 22/7 is an approximation that in many cases is close enough.  But, still there are other fractions that are closer, but do not quite get to an actual value.  

In addition, to divide a line segment into 10 parts is also more difficult with just a compass (divider) than it is to divide into 12 parts.  Sixteen parts is even easier, and is why we have pounds, ounces, and drams.

If you want to divide things into 10 parts each, there is the metric system.  Which, does have plenty of nice features.  Still, I think that Napoleon screwed up with it by not using base 12 (add the numbers dec and el for 10 and 11 respectively), and not basing the unit of length on the acceleration of gravity.  Imagine if the acceleration of gravity (on earth) were 12 meters per second squared, and that the meter divided into 12 parts, and each of those divided into 12 as well.  Then the unit of mass would follow the same principle with the base unit of mass (the gram) being 1/12 of a meter cubed. Science would be even easier than with the current metric system.

ETA, in base twelve, the word for twelve is "Doe", so you count one, two, . . . , dec, el, doe.  I'm no sure on how to get the symbols for dec and el on computer (I'm sure they are there in a character map somewhere).

All my tapes are in decimal feet.

We use base 10 because we have 10 fingers, not because it's the best choice for a numbering system.

But Pi isn't 22/7

Thank you.  

It should be all based on the nautical system.
360° in a circle or a sphere. Each degree is 60 minutes,  each minute is a nautical mile. Each nautical mile SHOULD be 1000 Fathoms. Each fathom should be 6' and each foot should be 1/2s, 1/4s, 1/8ths etcetera.

If there was only a unit system that was evenly divisible by increments of 10, I wonder what we would call such a system?

We'd call it divisible by ten.
