Wouldn't that depend on the screen size of the cell phone?
See, there is NO STANDARDS! And some keyboards are more precise than others, and some fingers are clumsy, while others are surgically precise.
That's why we have all sorts of different measuring systems!

Volvo, being made in Sweden, continued to use imperial in their cars until the late 70s. I had a 1974 Volvo 245 wagon that was easy to work on with my American tools and imperial nuts and bolts.
But yes, the issue is tooling, and the USA ain't no dinky little installed base of imperial-based hardware going back 150 years. Think of all those screw and bolt threads and pipe threads. It is happening in the USA, albeit slowly. Everything new in the USA is metric now. Vehicle speedos show both, but road signs and plumbing are still stubbornly imperial.
My toolbox at home is heavier than it needs to be because i have to keep both sets. Is it 17mm or 5/8" ?
The American aircraft industry is huge, including everything still in service from last Century.
Another advantage of Imperial measurements is their compatibility with fractions. Metric never works well with thirds, sixths etc. I find that both systems have a place, but don't try and mix them together.

I suggest real world is - metric easier.
10mm plus 19mm is way easier than 3/8" plus 3/4"
I do like having both sets though. you can use imperial drill bit for a hole to accept a metric bolt so it has a smidge of wiggle
75% is 3/4 but how do you accurately measure 1/3 using metric?
Pi can equal three and one seventh but comes up as a recurring number if you try to use a decimal number. (Pi is not Imperial but the idea that fractions relate better to Imperial measurements is the point)
Drill sizes are interesting because there are at least three systems...Metric, Imperial and Number drills.
I do agree that adding fractions can be harder, but some decimal numbers can be tricky too if you consider the use of thousandths. As such, engineering applications can benefit from both systems.
I went to school in the 1960's so I had to learn both systems. Some of the Imperial measurements have faded into history and are no longer relevant. I like metric but still use the old system for many applications.

A French aircraft designer, Marcel Dassault, designed his own screw heads. That was his standard so you had to buy his tooling if you wanted to fix those planes. Naturally, the Australian Government bought those aeroplanes (and the special tools as well). Perhaps it is the engineers fault that we have all this complication.

It's a businessman's fault . Engineers measure and fix the confusion.
All accurate measurements , ( metric and imperial ) , are done in decimal points not fractions .
Also , Pi isn't three and one seventh , it's close but still has recurring numbers. Just like decimal. The English didn't invent their sizing around Pi to nicely sit in at three and one seventh . It's just an ass that it's kind of close.
Learning to calculate and visualise metric is easier than fractions . That's why it's taking over , it makes more sense.
Also ,
Fractions can only accurately be used to describe length not measure it . Metric does both .
This is imperial for you . One inch can be broken down to halves , thirds , quarters , sixteenths , thirtytwoths, sixtyfourths , then if you need more accuracy it uses a decimal point . There are 12 inches in a foot , 5280 feet in a mile . It's all over the place like a mad woman's sh.t . No wonder they had to fix it .
As long as people try to say fractions is better than decimal , it is my duty to show otherwise .
Also suppose it points to the type of people/country you are, looking forward or looking back, collaborative or self-obsessed, maybe to lesser extent who you want to be associated with and how you do business. Here are all the countries still (mostly or officially) sticking to the imperial system and making ancient, inaccurate systems of measurement great again...

We have different measuring systems depending on our finger clumsiness ???
wouldn't surprise me, the foot depends on the length of somebody's foot back in time
Don't stop now IMAX. you are on the roll of the century.
- (Opps, is metric or imperial?)
To me Imperial is old habit and nostalgia.
If I go accurate I have to be decimal .
on the other hand I'll say move forward a foot or two , I relate to knots more easily than km. A bees dick is slightly less tham a smidge but more than fark all. When I look down in the shower I see inches not cm

I'm so glad nobody's mentioned gauge system . What knuckle invented that . That's dumb in reverse . In what world is a 12 gauge shot gun cartridge bigger than a 20 gauge ?
Stop me.
^^^ no that makes sense as it is the number of lead balls that size which make up a pound.
In old canon language it made sense.
I'm with you on fractions though. The only imperial I kinda like is thousands of an inch. Its easy to think of bigger thou' as its near enough 40 thou to a millimetre so talking about 20 thou overbore on an engine build is easy to visualise. And I therefore know that 'takingf a couple of thou off' is very close to a p00fteenth.
Old cannon language , so it was a drunken one eyed pirate with scurvy that came up with that ?

And the lead balls themselves became a handy measure of weight.
Whats the explanation for wire gauge

Sometimes I wonder if the US maintains the imperial system to subjugate the less educated.

You can't convert 1/3 to metric. You get a recurring number.

The metric system works for those who can use a base 10 system. It is short sighted to say that such a system is the best for all applications.

The Romans used to count in fives (base five) and computers use a base 2 (on/off) system. The Mayans used a system counting in 60. The decimal system is easy for us because we inherited the Hindu/Arabic system. The biggest advancement was when they started using a zero.
By the way, those who count in time (using seconds) are not using a decimal (base 10 system).
Musicians count using a range of fractions eg 4/4; 3/4 etc
The metric system is not perfect. The basic unit of mass is called a kilogram and has to be teamed up with plain old metres and seconds in calculations. (F=ma and all that). If you match kilograms up with kilometres and kiloseconds you'll be way out. ( 1 kilosecond = 16.666667 minutes )

But 1/3 is not a size or a measurement , it's just a description . It can't be used to do anything apart from visualise . If you needed to say add 1/3 or divide 1/3 it has to be done in decimal . 0.333 " recurring or 0.333cm recurring. The maths is the same . For example if you have a measured length of 7"5/977 th and you need to divide by 1/3 =. ?
The answer can be done , but then what do you do with it ? The fraction answer will be crazy with endless numbers . The answer can only be used in decimal format .
If you had a six pack of beer and three people , 1/3 is easy to visualise. But if you had 5 and 2/7 th of a beer and needed to divide between 3 people , not so easy . Decimal is the easy way .
