Yeah, probabaly.
I kept the periods because of the official packs solely.
...and although bit is compleltey offtopic,
Heh, I do feel we wouldn't be so bad off with an off-topic subforum.
While there certainly isn't too much need for it, it wouldn't hurt either, I guess.
Also, there aren't that many folks around which could making moderating such a forum hard work (I know what I'm talking about with moderating one of these at around 15,000 members...).
May have a chat with Bâshrat the Sneaky about it when the time is right (new site maybe).
Imperial measures advantage is their scaling in relation to real life, that metric doesn't have (I use both btw.) this is the best way to explain.
car tyre 30psi = 2.07bar
mountbike is 50 psi = 3.45bar
racing bike 120psi = 8.27 bar
the point being its easy to compare numbers on a scale of say 1 to 100 when the units fit the task. Metric units for things like trye pressures are useless, either in bar or N/m^2
I have to disagree with that.
The scaling is exactly the same, simply because 1 PSI ^= 0,069 bar.
This relation is absolutely linear with only one conversion factor.
If you take a closer look, 120 PSI is four times 30 PSI, while 8.27 bar is also four times 2.07 bar.
It may just not "stick out" that much because every second grader could tell you four times three is 12. And multiplying that by ten isn't magic, either.
HOWEVER, multiplying two by four and getting eight ain't so hard, either, same for seven times four equalling 27...
The only thing that's different is the period, but if you multiply by 100, it's gone, too.
Also, you're "cheating" a little.
You make the PSI values look integer while bar is "floating point".
This is merely because the company for the tyre is US-based and they used a value that is an integer to make it easier for the customer.
Guess what, over here, car tyres are supposed to be a straight 2 bar (unless you carry extra load, then it's 2.3 bar, at least for my car).
It doesn't really matter if there's some 10% more or less, most gauges probabaly aren't as accurate anyway (plus, temperature and current car load mean different pressure, too!).
What you did prove, though, is that the system you are used to is the easier one - there's no denying in that for sure! 
If I went to measure my car tyre pressure and found it was 1.93 bar , I really wouldn't know if that was about right or too flat becuase the difference in the two numbers is minimal. However if it was 25 psi I could easily see it was 5 out and what fraction that was of what it should be.
See, I know my tyres have to be 2 bar, that is easy enough for me to remember.
(and should I forget it, the values are on the inside of the filler cap 
).
Using a barometre to measure the tyre pressure, I get two scales (on the one I'm using):
One for bar and one for PSI.
While the difference from 2 bar to 1.93 bar may seem minimal, on the barometre, it is the same "distance" for the needle as it was from 25 PSI to 20 PSI. Hence, it does not require a better eye or a more precise measuring instrument. It's the same, just different figures (and colours for the scaling ).
I grew up using entirely metric measures yet now always use feet and inches for measuring 90% things because they fit the day to day sizes of things more sensibly.
That certainly depends, once again.
Remember that famous FMJ quote of "Four inches, Pvt. Pyle, four inches!" (for the distance of his weapon to his chest)?
Well, that would be a good 10cm in the metric system.
Maybe he would have less troubles remembering that? 
Also, when people guesstimate distances, they never are accurate.
You use whatever is closest to an integer figure of your measurement system.
If I was to give the distance from my home to the train station, I would probabaly say about 1 km.
In reality, it's more like 1.2 km.
Now, you'd probabaly call that almost a mile.
Neither comes really close, but it's not important to be more precise in these things.
Of course, it's easier to say two feet instead of 0.6 m; you'd make that 0.5 m more likely.
If you want precission, you'd say it in mm anyway, and that is a lot more precise than inches
Unless you have used both systems you perhaps cannot understand this though [ I tried explaining it to my gf once who only ever used metric and she couldn't 'get it'.]
Well, probabaly, but I wager to guess that I know more about the Imperial System than the average German or continental European.
Also, I am somewhat interested in "ancient" measurement systems (Inch and feet were both known in Germany for a very long time through the Middle Ages up to the 19th centruy when Napoléon made several reforms).
In fact, pound is still being used every day, although, over here it is an exact 500 g or 0.5 kg so it's pretty easy to do that conversion).
As I said before, it really comes down to what you are used to and what is commonly used in your environment (funnily, I strangely had a harder time readopting to the right-lane system after having spend some time in the UK than I had adopting to the left-lane one... ).
As a final note, the one perfect reason to use YYYY-MM-DD is that whenever you use MM-DD or DD-MM on the internet I spend at least half a minute trying to find out which one is meant if both figures are >= 12.
Very annoying!
As there is no YYYY-DD-MM, this system simply avoids any confusion whatsoever (that is to mean there's only one way to interpret this, it may still confuse you if you do not know the scheme, of course).
