Look you metricians: the definition of your centimetre is:
the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second
divided by 100. Nice one. Very everyday. Great for scientists. Meaningless for the hoi polloi. I'll take my inches any day.

What I find curious is whether you googled the definition of the inch? ;)

I don't need to, if you are English you can inherently sense what an inch is.EDIT
So I looked at your reference:Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and defined as exactly 25.4 mm.
Typical. That is the metric inch. Not the real inch.

Why bother to google something so obvious? Everyone knows that an inch is 1/12 of a foot.

That would be a unit conversion, not a definition. Just like the centimetre is a tenth of the meter (centi- is the giveaway here).

lol.

Another reason not to trust metric. Simplicity of the math encourages laziness of thought, leading to this kind of error :) Imperial arithmetic keeps you on your toes....

@kshegunov & @Chris-Kawa
Brilliant! I admit I didn't know about all those other measurements. They all seem to make real-world sense to me, and I'm even more impressed by the Imperial system than I was! :)Just for example. A pint is the natural size to drink beer in a pub. A litre means nothing, and is too big. I rest my case.

yes but! Have you ever been in a pub that actually pours a pint? Of course not, if any person behind a bar stops at the pint line they will be covered in tar and feathers and trotted down the high road in a walk of shame. They pour to the point of overflowing (and rightly so) which usually is... half of a litre.

In between us girls...
I find Qt (C++) very versatile , but from get go frustrating to "download" and it is not a problem of licensing.
After one gets a Qt account there are uncounted ways to actually get to the correct place to load "archive".
It gives poor impression about the vendor.
Let me out another spin on this "poor impression".
My background is in communication - telecommunication - telephony to be precise.
I came to US with "year 1940 knowledge of mechanical switching system (relays) and retired after ushering few computerized , transistorized , IC 's , fiber optic etc etc "stuff" .
In "before internet " US telephone service was top, almost every business had an operator to assist the customer...
Now try call and conduct serious business.... first you get "...our options has changed...for English press..."
Why am I saying this? I am trying to draw a parallel between "download Qt" and trying to get a live person to assist with telephone inquiry.
That is all I am saying. -

Years ago a restaurant tried to introduce the 1/3 pounder. Nobody wanted to buy it as they thought a 1/4 pounder was bigger. Because 4 is bigger than 3. I wish I were making this up. Can you expect a population to accept metric over inch when those kinds of issues are going on? Also, there are millions of feet of imperially spec'd infrastructure installed. That is never going away. The best you can hope for is some hybrid at this point.

Let me throw you a bone (the political kind):
"The biggest problem of Bulgaria is the bad (quality of the) human material in the country" ~B. Borissov, 2009For context:
B. Borissov had been the PM of Bulgaria for 12 years bar the last few months. So be optimistic - it can always get/be worse. ;) -

One of my ham radio hobbies is to play with antennas.
For an antenna to be effective its basic dimensions are related to frequency in use. The frequency is stated in meters or hertz.
Pretty much acceptable in Imperial or metric system.
I have never seen a radio dial marked in "feet per second ( seconds are imperial ) " .
But vast majority of US amateur radio enthusiasts measures antenna dimensions in feet and fraction of inches...memorizing some "magic numbers " formulas and struggling with adjustment in percentage ( metric ?) of fraction of feet and inches.
BTW my insulin is measured in 100 units = 3 ml . go figure.And since we mentioned "culture" "anomalies"
what is better a "warm pint" or "cold half a liter " ?Cheers

@sierdzio Of course it is. But when temperature drops below -10C one might want to switch to spirits.

When it drops under -10, you may want to switch to antifreeze ... ;)

Often units are defined as it is convenient, even conversions, so I suppose that's the most easy for the reader of said test. In nuclear physics it's ubiquitous to measure mass (and momentum) in eV, which is a unit of energy; it's simply convenient to put the speed of light to equal 1. That nonsense even has a name: "natural units". -

Absolutely. Can you remind me: when I ask for a pound of butter at the shops, how much should I ask for that in that useful eV? -
@kshegunov

Can you remind me: when I ask for a pound of butter at the shops, how much should I ask for that in that useful eV?Can't give you an exact figure, but I'd imagine somewhere between 1 exa electron volt to a few zetta electron volts. Of course I'd suggest you don't get a pound of butter to begin with, but you better discuss this with your doctor. ;)

I'm spoiled by supermarkets. I don't have to ask anyone and thus don't have to think about units at all most of the time. I just take a look - "that's about right" - and take it off the shelf :) Come to think about it I do it a lot - amount of beer, tire pressure in my bike, shoe size, water temperature for swimming, time spent coding...
Yes, "that's about right" is my daily driver unit :) -

I've read an article recently that people on average are superb predictors of probabilities, if the prob. density is symmetric. We fail rather miserably when the statistics is very skewed though. I found this very interesting - we tend to identify and predict additive factors excellently by intuition, but we are not so good when the dependency is multiplicative ...
