Metric vs. Imperial in your country?
-
Thank you for your answer.
At least in my country, people think in either meters (the building and rooms) or centimeters (the details). Nobody thinks in 10's of cm, but we do try to keep all measurements rounded to the nearest tenth of a meter while designing, because walls are usually drafted as either 10cm or 20cm (even if in reality they're slightly thicker). This is only broken in stairs: Raisers are usually 18cm, but I prefer 17.5cm as it's easier to convert to Imperial.
Architectural plans are all in decimal meters (not cm), while engineering plans are in millimeters.

The UK is officially metric.
It changed when I left school.
Our applied maths was in imperial [BTUs, horsepower, foot-poundals etc]
Our physics was in cm/gram/sec, but that changed to SI m/kg/sec !
The year I started to train as an architect the building industry 'went metric'.
Drawing scales changed from 1/8":1' [1:96] to 1:100 etc.
All architect and engineers' drawings use mm to nearest mm and no units suffix - except where it avoids confusion.
UK land surveyors use m - just to confuse us.
They also want sq'/acres as well as the now mandatory sqm/hectares
Bills of materials are measured in nr/m/sqm/cum
Outside of construction day-to-day units are cm/m but often with dual measurements.Over time materials like bricks were metricated - so a brick is now 215x103x65with 10mm joints, rather that 9" etc.
Older people still talk of a 9" wall when they know it'll be 215mm.
Most can think in both systems as appropriate.
Youngsters are only taught metric at school, so sometimes imperial is more of a mystery to them...
Timber also got metricated sp 4x2" sold in feet, became 100x50mm solid in 300mm length incrementsAt home most houses use metric doors e.g. 2'6" rather than the metric equivalent [used 'commercially'] - which need a special order - merchants stock imperial sizes but label them both ways - e.g. 762mm.
We weigh ourselves in 'stones' 14lbs=1stone, rather than kg - or the US's lbs.
We usually think of out height in '/" rather than cm.
Clothes are sized in both inches and cm - so 36"/91cm etc.We drink pints of beer in the pub.
We buy fruit/vegetables in kg or pounds and dual scales are common - although to comply with EU rules the minimum is kg, pricing is often dual too £x/kg:£y/lb
We buy petrol in litres, but use mpg for our car's fuel efficiency - distances are sign-posted in miles and all speeds limits are in mph.
We now use Celsius for temperatures etc.
We also went decimal with our currency in 1971: so now £1 == 100pence, with notes for £ 5/10/20/50 [£5 & £10 are now plastic with £30 changing soon] and coins for £1/£2 and 50/20/10/5/2/1p
Previously £1 == 20 shillings and 1 shilling == 12 pence
With some weird things - like a crown [5s], half-crown [2/6], florin [2s labeled as 1/10 of a pound], 1s, 6p, 3p, 1p, 1/2p and a farthing [worth 1/4p], there were also 10s and £1 notes.So all in all it was a confusing time and we are now pretty much 'bi-metrical'...

We are metric in Ireland but tend to be bi-metrical as TIG says.
Although still use imperial to describe distances.
Thanks the EU we have this silly mixture of imperial and metric. Oh and straight bananas.

And straight cucumbers !

So on the job site is it a little wordy when you can't say 2x4 and 4x8 any more? I suppose you can still say (in the UK) a door is 2868? There are a lot of established shorthand standards in imperial, e.g. concrete mix 5 sacks/cubic yard, 8x16 conc. blocks. 4x8 sheets of plywood, #4 rebar. And nails or screws: 10d and #8, all somehow based on imperial standards.

A little fun fact that you might get surprised: US is officially on metric system!
Take a look at below video for an authorized person at the National Institute for Standarts and Technology (NIST) comment on this:
@unknownuser said:
All the units that we commonly use like feet and gallons and so on are actually defined in terms of metric units so it's just a little translation that we do here but our country is actually on the metric system.
I suggest watching whole video but espcially for the quote watch between 0:31 - 1:25

France was creating metric system in 1799 from a Burattini research (1675) so... only metric of course!
Last reform was Francs / Euros for nasty money business ! (1999)

In France you can still go to the market and ask for a 'pound of carrots' [une livre de carottes...], and expect to get about half a kilo.
Since a quantity of carrots is unlikely to weigh an exact amount being overly accurate is pointless
I expect most youngsters will think and ask in kilos/gms ?
In the UK us elders ask for a 'pound' never half a kilo !
As an aside it reminds me of a joke...
Wife sends husband to the market with a shopping list.
He returns with a sack of carrots.
She says, "Why did you buy so many carrots?"
He says, "Your list said you wanted 116 carrots!"
She says, "That's '1lb carrots' !! Doh !!!" -
We prefere say "500 grammes" and if need more precise "450 grammes"
"Livre" is for old generation! -
I am the 'old generation' !

Long live the pint!

When the UK went decimal for currency there was an immediate rise in prices that did not seem to be noticed. The price of a box of matches went from one penny to between two and three new pence. Just an example. The suggested equivalency at the time was that one new penny equaled two pennies. I know it does not make sense.

I was introduced to the metric system in the late 70s, in elementary school science class - it was the billed as the wave of the future. I'm guessing that wave kinda dissipated by the time it reached U.S. shores. Some metric units have creeped in, such as 2 liter soda bottles, nutritional value units, and computer capacity measurements, I'm guessing its because either those measurements didn't exist previously or no one paid attention to them. They tried selling milk by the liter, but that never caught on. We remain very much "imperial." And, personally, I hope they don't change in my lifetime, as feet, inches, and fractions thereof are second nature to me. Architectural specifications sometimes have both units, but I stopped including metric when typing them up myself.
