"You"is whoever is reading this post. Nothing in US Law is stopping you:
When Uncle Sam is using his computer he is using the metric (SI) system, (probably without knowing it)
Thank God ( The EU and the UK) we can still get a pint of beer
One system = No conversion required. That is a no brainer.
If you order âa pintâ in a pub in any EU country (other than Ireland maybe) you will get a glass containing 0.5 Ltr. (500 ml) which is the nearest eqv. to both an Imperial pint (568 ml) and the US liquid pint (473 ml).
PS> Not to be confused with the US dry pint (551 ml)
Canada, Australia, South Africa, New Zealand and Singapore converted to the metric system in the 1960s and 1970s; so while the term pint may still be in common use in these countries, it may no longer refer to the British imperial pint once used throughout the British Empire.
I did not know that. I think every program and plotter I have lets me set the units, depth is a data field on a vector chart and can be converted easily.
Still the color thing works for everyone, set it right and stay out of the shallow colors 
In school we learned the metric system because we were about to switch. Then that never happened 
Thatâs because us little-boat drivers use âchartplottersâ while the big iron boys have an ECDIS. Apparently, they arenât as flexible. We use feet on our vessel - but when I get the Explorer charts for the Bahamas out, theyâre in metric -not a problem, though, as they are well marked.
Why? Because I, as an American, have gotten used to using whatever measurement system works best - when I was in the Army (71-79), all land navigation was metric (but the payload capacity was in pounds/imperial tons because that was what was on the placard). On the boat, itâs nautical miles & knots, but I can handle statute miles or depths in meters, fathoms or feet. Iâve bought cheese, milk, beer and all manner of things in imperial and metric - never had an issue. Pretty much everything in an American grocery store except bulk goods is marked in both systems anyway. My wife (who went to med school in Europe) doesnât have any issues with any of this either.
Do not get me started on obscure threading systems, plumbing sizes or metric frigginâ time.
I do have a question for Mr. Bugge, though - other than some sort of annoyance about people who refuse to think exactly like yourself, why would you possibly care whether Iâm buying cheese in pounds or kilograms?
Iâm not annoyed by those who donât think like me, or refuse to see thing my way, nor have I expressed any annoyance at anybody for disagreeing with my.
If everybody here agreed on everything, this would be a VERY boring forum.
Letâs agree to disagree, but I reserve the right to have an opinion without being made out to be some sort of imbecile that canât understand otherâs point of view.
PS> I donât care how, where, or what kind of cheese you buy, as long as you enjoy itâŚ
Bug
I am British
I buy my fuel in liters.
I measure my cubic capacity in litres.
But I measure my fuel efficiency in miles per gallon.
Go figure
And best of all I buy a pint of beer,
Not that many panmby lager stuff the rest of the world seems to think Is beer
I do not know or rather do not understand your fixation with this metric system and your passion to convince Americans to change their measurement system to SI . I do not give a ratâs ass abt it. Nobody except You is complaining. If they are happy with it leave them alone.
Besides few days ago i got a conversation with a plumber to plan some repairs at home. He gave me a ilst of items to buy in âhome depotâ - we have OBI, Leroy Merlin and similar and on the list all the pipes , fittings , connectors , splits , extentions , all this stuff is in 1/2 inch , 3/4 inch 1 inch .
Believe me or not, if he gave me all this measurements in milimeters i would be at a loss and i am sure i would piss off the vendors with some stupid figures in mm, when all what they have on the shelves is in effing inches . How about that. ??
Now why are You not complaining about Nautical miles, knots , cables, shackles???
Can You imagine how pissed off I would be if some smart ass rookie navigator will inform me during my morning coffee on the bridge ,that we are making 45 km/hr or that my dist. run at noon was 850 kilometers.
With their foot,feet , inches, fathoms and yards they had made it first to the moon , built space shuttle, and made the first ENIAC and built the first atomic bomb and it worked for Gods sake. They even docked with Soyuz during cold war.
And one more thing. Everybody loves their ARMS . !!! F35s, B1s, raptors , Târexes , pterodactiyles or even B52s . 
., Patriot batteries , Himars ,Abrams you name it. And nobody is bothered by the inches and yards here . All are buying like crazy .
My gov. has contracted for abt 200+ Abrams and they do not care about all the logistical problems it would create regarding maintenance , production of spares , inventories , support equipment , tools, as one has to create mini industry to take care for these babies , train people etc, etc . And all this is related to inch/feet/yard problem.
The only thing that worries them though is , they have already seen some Abrams wrecks in Ukraine damaged by ruskieâs 5 dollar drones . And this is a real problem -not the yards , feet and inches.
To support the ARMS thing i have dug out something from your nordic environment .

Impresive !!! is it not ??

I like framing any additions/new construction/re-mods on 16" centers, thank you very much.
Some of my fishing tackle needs metric sockets, some ImperialâŚI just donât care. What it takes to do the job. It really isnât that hard.
I would be amazed if anyone using this forum isnât already used to a 24 hour clock. Thatâs an example of why so maybe of your posts seem so arrogantly ignorant.
Youâd think so, but meters and decimeters do not convert nicely to feet. There would be a lot of automated rounding, which would decrease accuracy for ENCs made in meters when prudence would dictate rounding in a fail-safe manner leading to more alarm fatigue or stress on big jobs. Itâs like when there is a wreck in 500â of water with an unknown depth, reported in 1963 thatâs going to alarm every time even though itâs unlikely itâs a ship doing a headstand for 70 years.
Not that charts have ever been that accurate, but with metric being more precise, I could see why they wouldnât allow it.
Interesting thread and viewpoints. I think it really does not matter as most people (just as language if you know more than 1) âthinkâ in certain units. For example, they may think length in feet, temp in C, weight in whatever ⌠and convert in their head almost immediately. This is very simple for the human brain â all the brain needs is a reference point to gauge. If you say 10 meters, people who think in feet will immediately get an idea by converting to about 30 feet.
PS: Capt Bugge - Ever wonder why in Norway, your car wheels/rims are in inches? And if you shop for tires it is a mix of diameter in inches, width in mm and aspect ratio that is unitless âŚ. Go figure âŚ
PPS: BTW why metric and not SI units? Yet another standard
Was that all you got out of a post about Radians, Metric time and Unix time?
Probably true, but AM & PM is still widely used by the majority in daily life in many Anglophile countries.
You frequently see and hear even â10 AM in the morningâ used by people and media.
PS> My reply was to âPoweraboutâ who is an Aussie and live in Singapore, both Anglophile countries.
I agree but if someone who âthinkâsâ in one system becomes immersed in another, say at work for example, itâs relativity easy to switch or use either once it becomes a habit.
24 hour clock is for people that like giving out incorrect ETAs.
I got that sweet 12 hour cushion.
My understanding is that itâs not a lack of flexibility but a deliberate decision to lock out any options except meters. This is to avoid the possibly of errors.
But its really 32â 9" which is a bit of a difference when you have 3â or 1 meter UKC policy.
