Neat ! Gradians

Ok, that's on me, I knew that existed. I meant adopt a metric time system.

because celcius is about how aater feels, faranheit is about how you feel and kelvin is about how atoms feel
every "you" is subjective, water is not.

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.
Yeah, but let's see if they get the apple example before we throw all that at them.

L nationality and its system its trying to uphold, barbaric concept about to or at the finishing line to end our very existence through its "interests"

It's the size of a thumb. The Dutch translation is "duim". These smaller units use tangible things to measure. A foot and a thumb is always on you.
Its the size of Kings thumb, so I guess it suits for USA now, when they have one.

But why? Binary is a better basis for numbering, when I was demo coding in assembler on the Commodore 64, I learned a technique to vastly speed up trig calculations: divide the circle into 256 degrees, you can use simple 8 bit integer math to blast out sine values.
I figure the same should go with time. It's not like we still use our fingers to count. -
The biggest issue with imperial recipes is the constant use of measures by volume. If everything was in weight ounces it would be alright, but a lot of recipes insist on measuring solids by volume, like a cup of flour, a teaspoon of sugar etc, making them a lot harder to replicate consistently. My flour could be denser, my sugar could be finer, if things were measure by the actual mass such things would not matter but instead I have to fill a cup and pray to the gods that my cup of Ecuadorian flour has the same density as the one on the recipe (it almost never is)
Surely using oz & lbs on a scale solves this?

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.
That's my point. You essentially need to add a qualifying statement to make decimal work, and even then people don't naturally understand the precision. In your example, most people think the precision is the last bit (.02), whereas it's actually .04 since it represents the error on either side of the measurement.

That's the whole point, the recipes aren't in oz and pounds, they're in cups and table/teaspoons

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 ± 0,00005I have a set of precision digital calipers that shows decimal or fractional units. Verus a worse set of calipers that'snot 10x worse, it shows exactly the same measurements in decimal units, but with fractional units it will show a difference because that difference can be represented.

I figure the same should go with time. It's not like we still use our fingers to count.Meanwhile, me counting to 4 in base two using my fingers.

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 €.
I understand sig figs. That's my entire point. What I'm saying is that fractions don't require the use of sig figs, and especially don't need any "+/-" bullshit at the end when precision isn't measures at a granularity that isn't a perfect power of 10.

Come up with a metric time system then. Also, fix the damn calendar.
Why would you want to change the time system? The whole world agrees on the current system

How do you define inch without metric units? How much is that?
Every country has a different definition of inch.
It was a beautiful chaos before metric!

Is there anyone in this world needs a caliper of precision between 1cm and 1mm that can't afford a 1mm of precision caliper?

Kilometers to miles is probably the easiest common conversion. 5 km is 3 miles, easy peasy.
Except 5km is not 3 miles... it's 3.1069 miles so off by a considerable factor. 1 mile = 1.6km is a much more accurate approximation that's easy to remember.

I'm accustomed to the imperial system. But agree that metric is better.
Some metric stuff I have no trouble with. I have a good spatial sense of the distance of a mm, m, and km. And can do a rough miles to km (and vice versa) conversion in my head. I have a good sense of how much a kg is and similarly can do a rough conversion to and from lbs in my head. But while I understand that a gram is 1/1000 of a kg, if handed a small object and asked to guess how many grams it is, I'd fail miserably.
Celsius I can't ever remember the conversion, but I've had enough exposure to it that I understand if it means cold/cool/warm/hot weather.
Everyone in metric zone fails as well to guess weights of a few grams
best I can do is estimate 1/4 kilos -
The one thing that bothers me about the metric system is how much of it is never actually used. No one says "1 megameter", for example. They say "1,000 kilometers". When you think about it, most metric prefixes are never used with most metric units.
Similarly, how the kilogram is the SI unit for weight, not the gram.

every "you" is subjective, water is not.
Water has different boiling and freezing temperatures depending on salinity, alcohol content, and atmospheric pressure.
The 0 is freezing 100 is boiling is a good rough estimate but it's not a universal law.
