I'm fairly sure most people in this newsgroup do, tho.
And the point is? I can easily switch between metric and imperial (and between imperial and US units for that matter, just like I switch from English english to US english).
There is no particular advantage to using metric (which is Leon's point). If something is in imperial units, I use imperial; if it's in metric, I use metric. I see no reason to convert one to the other (unless directly comparing two things in different units).

But all of those were, at some point in time, defined by some physical thing in common use, and were fairly intuitive to their users (especially in medieval times, when counting by twelves was common and counting by tens wasn't).
There's no way you can say a tiny fraction of the distance from the pole to the equator is intuitive.
Of course, just like Leon's initial example of converting _from_ imperial to metric, it's no more difficult to go the other way if were to really, really want (or need) to...
...
The key is the latter--we don't set out to the store to buy precisely a liter, we can only buy the container that's on the shelves. The manufacturers made the shift for one reason to satisfy the mandate of the EU that required it and doing so; it's only economic to have one production line for a given nominal size. It's fortunate that a liter is roughly 1 US qt (within about 5%) so it is essentially transparent.
But, ever hear anybody take that and say they're going run out and get
2L of milk? No, the innate volume reference of the US population is still the qt and 1/2- and 1 gallon milk bottle/carton and likely always will be.
It's a single base rather than multiple bases (ten and whatever divisor needed for the precision needed - 2/4/6/16/32). Imperial can be made easier by limiting the bases to 10 (drop feet) and use only one divisor (e.g. use 24/32 rather than 3/4 and do the arithmetic on the numerator only).

That's because it isn't. Floating around somewhere is a Metric vs Imperial comparison, where it says one system is better because of some reason, then not long after says the other system is better because of the same reason.
A quick Google didn't return anything like it, and it wasn't on the repairfaq.org humor page. (Don't go there if you don't have some time to kill... you'll be busy reading jokes for an hour or better.)

Since they turned off the "selective availabilty" (or whatever they called it - the intentional error that the US military insisted be inserted into the GPS signal for non-military uses) 10 feet (or 3000mm) would be about right for horizontal measurement. GPS it quite a bit less accurate vertically without special processing.
Reliably resolving below 10 ft without using differential (or "relative") techniques is still a bit of a problem.
No, that's not it. That is how to up grade the fingers of your DT jig to a later version past the D4. You can buy the new set of fingers that are identical in size and shape, except for the extra holes in the set or you can make yours the same by drilling the hikes in those odd sizes and locations.
It was always written "um" and is still spoken as "micron". Nothing has changed at all. The unit is *not* left off unless the context makes is perfectly clear. ...no different than any other unit. You don't say "two feet, one inch, and three eighths of an inch", rater "two feet, one and three eighths". No difference.
Then the more likely explanation, the rest of the world is not smart enough to use Imperial and fractions.
We in the U.S. Measure in whole numbers, just like with metric, and in fractions. The rest of the world complains about having to use fractions. We complain about the rest of the world because we don't want to measure in only a few resolutions.
We look at the length of a piece of wood as perhaps 95 -1/2". or 96". Metric users think 2438 millimeters or may be 2400 mm.
That would be like us measuring that length as about 1520 sixteenths.
It may be that metric is preferred for the rest of the world because it works with all of your fingers for adding and subtraction. :-). Metric is truly easier but not necessarily better.
Concerning your comment above about you being able to switch from English english and US English. And I am poking fun here with this question.
The English english words, bird and the name Mark. When we hear the English english version of both words we hear "bud" and "Mahk". Do you guys use the letter "r" with in a word? ;~)
Y'all may now ask me a question about how we pronounce words in Texas. LOL
I'm positive of it for the bulk (as in essentially all) of the regulars. The drop-ins are something can't tell about, of course.
The other thing of the wreck w/ the regulars (and much of usenet) is that the regulars are of a certain age that most likely also colors most responses in such categories of discussion as this thread...
An oddly pleasant and distant memory of mine from my early childhood. I was probably 4~5 years old.
I recall my parents doing yard work and me being in the middle of it all. It was a fun time for me because I got to watch dad and hopefully help dad mow the yard with the gas powered reel mower. The mower was exceptionally easy to control, I could do it all by my self. Starting the motor was another matter as it required wrapping a rope around a pulley and giving a forceful and full pull and repeating several times. The wind up lever handle had not yet come to market.
I recall the 1 gallon dented red metallic "Gasoline" can that had an internal and reversible metal flexible nozzle with a strainer on the top end when it was stored in the can. And the strainer end had a small metal screw cap the same size as the metal screw cap for the vent on the other side of the carry handle on the top of the can. And with the exception of the paint and cork gaskets, it was all steel.
Anyway I always did and still think of that dented red metallic gas can when I picture the size of a gallon. ;~)
