Ask an average American to give you the length of their car, size of their kitchen or weight of a brick in metric and they'll have no clue. The average British person can do this, because education has been metric for 50+ years and the least-technical industry (e.g. construction, DIY) is metric.
(See e.g. https://www.diy.com/, the largest consumer-facing DIY shop in Britain. It's 20kg of 10mm gravel, doors in millimetres, paint in litres. I can't even see a button offering an imperial conversion.)
The USA only uses metric in some important industries.
Britain uses it for lots of "unimportant" things, like construction/DIY, medicine, health care, cooking, sport/fitness.
I’m not really sure what your point is. If we take as a starting point that the US used the metric system where it matters, then why is it an issue that it isn’t used ubiquitously? I’m not saying you need to agree with the claim “the US used the metric where it matters”, but if we just take that on face value, then why isn’t that enough? Why do you care if Americans talking amongst themselves speak in their own vernacular and system of measurements? What exactly is the problem?
That is not true -- it's in a different middle ground, much further from a fully-metric country. That's all my point was.
> Why do you care if Americans talking amongst themselves speak in their own vernacular and system of measurements?
It's fine if they keep it to themselves. I'm never bothered by traditional Japanese floor area measurements, for example. But Americans attempt to use their own, private system when communicating to the rest of the world, in commerce, software and media. (Search "Weather Taipei" on Google while in Taiwan, with a browser set to not-US-English, and you end up with Fahrenheit etc. Set Windows to "English Ireland" and random bits of stuff will still be in miles/°F.)
This even leaks to non-Americans (or maybe English translators). It's annoying to go to a museum in, say, Brazil and see the Portuguese text uses metric, but this has been translated to pounds and feet in the English text. Most of the tourists reading the English aren't even American!
What’s the difference between that and when the rest of the world tries to communicate with Americans using metric? In my experience foreigners in the US complain significantly more about the US not using metric while in the US than Americans do while in countries using metric.

Can you not set your choice of units as a preference? Or are you annoyed that Google chose a default that is different than the one you wish to see? Given there is no universal choice that pleases everyone, wouldn’t their choice annoy some people no matter what? In any case, this is a complain to direct to Google and not Americans in general. Besides you’re free to use another weather app that matches your defaults.

This is a complaint that should be directed at a certain Brazilian museum.
