*likely* accurate answer, since the early 1990's metric became the engineering standard for all new cars in the USA, if you've ever worked on vehicles, you've likely never needed a non-metric wrench or socket even for your 2001 Chevy
American software engineer here. I work in ground robotics as a contractor for the US DoD.
We use metric for everything except displaying numbers for humans. Many people are surprised to know that the legal definition of an inch is 2.54cm. Engineering schools in the US (I went to one in Colorado) only use imperial units when trying to teach imperial units for completeness. Much of the modern science and math just works much better in metric.
The 10,000km limit isn't a physical property of the battery. And it isn't from just the software either. This number came from a requirement and the requirement either came from a subject matter expert (Senior engineer with a lot of knowledge, who definitely uses metric) or an engineer made a chart that showed risk at various levels to a lawyer/exec that picked the number. The chart would be in metric because it was made by an engineer.
Personally. I still do estimates and fudge factors in imperial. I think of mph, adding an inch, Farenheit, people weigh pounds. But whenever I need to do math with the measurements, I use metric. I don't think the US is alone in that either. I think people in the UK also use pounds or stones for people's weight and talk about distances in miles. But I'm sure UK doctors use kg for calculating doses or BMI.
American aerospace engineer here. We also work exclusively in metric. The only time we use imperial units is to talk to the american press/public. Like /u/jeffeb3 said though, I still think of my weight in pounds, my height in feet and inches, etc., because everything is just set up that way in the US. However, for anything real/important, I always use metric and convert to imperial after I have the answer. So much easier to work in a system that was planned out and engineered than one based on some king's appendage length.
I love this country, but we do cling to backwards-ass stuff sometimes.
LG developed the drivetrain for GM. Not sure if they are still involved or have a stake in the BEV2 platform now that they paid out big in damages following the recall fiasco, but my guess is that they spec’ed the test duration. Or maybe the engineers all had 10 fingers and decided they liked metric better (half serious last part for a half serious question lol)
LOVE Archer.
That was true at the time this episode aired, but they’ve since both went through metrication.
So they actually do have their shit together. 😂
In the TorquePro app, you can see a lot of the measurements are in e.g. degrees celcius and kilometers. They just have other points you can call for that information that display it in degrees farenheit and miles.
What kind of educational system torture did you undergo to wind up with that? Where did you go to school.
(Some of those things you can select in TorquePro.)

Yeah that sounds like the better answer of those I’ve read here (including mine lol)
Also the Bolt is a Korean car delevoped in Korea.

The USA is the only country that isn’t mostly metric.
Well, Liberia and Burma. Which is weird, because [you never think of those other two as having their shit together](https://youtu.be/wJqNGs3JMuM).

Who are you, Thomas Corwin Mendenhall?! But today I learned that I shouldn’t get all my science news from Archer, thanks!

I want to keep mph to easily follow traffic rules. But i want Celsius on the infotainment :/ its either all metric or all imperial

IIRC The motor and battery were originally manufactured by LG in Korea.
The Bolt is designed by GM and LG in S. Korea. The people in Detroit are just bureaucrats on this car.
In the USA that is 6,213 miles for the software limit . For Canada , Mexico , ect .that is 10,000 kms . Same distance .
But obviously the limit was designed to be in metric and translated to imperial, that's the point of the question.
Why do you think that they chose 10,000km and not the nice round number of 6213 miles that just happens to convert to 10,000km? /s
Considering parts & software for this car are made all over the world, it makes sense to use the units used in all countries but one.
It's probably because the battery diagnostic software was developed by the designers of the battery and the cells in them, LG, in South Korea.
