Is there anyone in this world needs a caliper of precision between 1cm and 1mm that can't afford a 1mm of precision caliper?
If you have 0,7 that is more precise than 0,7 and less precise than 0,7. You can just say 0,7 ± 0,02.
As I said in another (larger) comment, you just don't know how precision is encoded in decimals, which doesn't mean that it isn't. In fact, precision is encoded in decimals, just like with fractions.
0,7 is 0,7 ± 0,05 0,7000 is 0,7 ± 0,00005
That is not a flaw of decimals. It is a flaw of you not knowing how precision is encoded in decimals.
0,7583 means 0,7583 ± 0,00005.
0,758300 means 0,75833 ± 0,0000005.
0,76 means 0,76 ± 0,005.
That is why when in a store an item costs 7,5€, we don't say 7,5€. We say 7,50€. Because it is precise to a hundredth of a €, not a tenth of a €.
1/14. Easy
If programs can handle February having 28 days, sometimes 29. It can handle 14 having 1 day, sometimes 2.
Precision has nothing to do with the unit system. Or notation of fractions.
0,001m is as precise as 1mm
1/1000m is as precise as 1mm
In SI you don't even have prefixes, you use scientific notation with base units. You don't say neither 1mm nor 0,001m. You say 1x10^-3^. Which is exactly the same as the other magnitudes of this comment.
If you want precision in imperial, you could as easily say 0,00000000001 inch. It would be as precise as 0,000000000255 mm, or whatever the conversion is.
"deci" is very popular. Just not in the "correct" form "decimeter".
In Spanish it's normal to say "8 décimas", which means 8 tenths. It is context dependent though. For example if speaking in a context where millimeters are used, it will be 8 tenths of a milimiter. That is, 0,8mm.
But yeah, it is very uncommon to use deci and deca. Because they're just not very useful. We are used to 2 digit numbers, or numbers with 2 decimal places. So 87m is not harder to use than 8,7dam.
It's probably also the reason there is no prefix between kilo and mega, or milli and micro. (They are x1000 increments instead of x10).
For the same reason, when in a context of millimeters, it's preferred to say "87mm" instead of "8,7cm".
It's even worse than that. They increase the price right after they increase the ad length. As in "well, now that ads are longer, this subscription has more value. Therefore we should increase the price".
You have to trust them though. That's my point.They may say they are funded only by donations and still sell your data.
In fact the first link says the same as I do as the first phrase. When using a VPN, you are moving your trust from your ISP to your VPN provider.
Of course there may be exceptions that are actually free and don't sell your data. But the ones that sell your data will rarely state so.
Idk what either of those are. I don't endorse any VPN. All I'm saying is that it doesn't matter how strong the encryption algorithm is, you still have to trust your provider.
VPNs have the exact same power over you as ISPs. Using a VPN to avoid your ISP is just kicking the can down the road. That's why you better choose a VPN that you trust.

And that is shown by the markings.
I just looked one up, it's less than 20€, 0,02mm of precision. There are just 4 markings between 1mm and the next.
So instead of 9 markings, each marking adding 0,01mm, you just add 0,02mm. Doesn't sound complicated at all.
I haven't found an analog one, but a digital one with 0,01mm of precision costs 30€. Maybe an analog one costs 50€.
So if adding 0,02 is too complicated, you can just buy a 0,01 one for 30€ more. Which is the price of a pizza for a tool that will last years.
Anything more precise than 0,01. You probably have a lot of experience using a caliper. Whatever method it uses to display that precision is gonna be second nature.
