A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

I say that Metric is like color vision. You can see things in whole new and easier ways. People in USC can't understand what others see and insist things are just fine the way they are. Thus the "no one ever does that", "why would you need to know that", "who cares", etc.
It is true that no one ever does that though. That doesn't mean its not a problem, but I've never seen anyone do it. If you need to do something like that and you have a brain, you use metric. Just because its flawed doesn't mean imperial should be completely abolished though. What needs to stop is people thinking imperial is better than metric somehow. Aside from that, its just a weird flawed measurement system.
We don't use imperial in the US, we use US customary. Some units have different sizes in imperial. For example, a US pint is 16oz and an imperial pint is 20oz.
That's how they get you. They make the beer smaller.
Yes: For woodworkers, it's identical to 6.5mm, accurately eyeballed at between 6 and 5mm. Don't pretend you're a machinist. Does your tape measure even have a vernier scale. Does it make satisfying clicks when measuring. If you have a slip instead of interference fit just dump one piece in water for a second it'll be fine.
To be more precise, it should be rounded as 6.7 cm, accurately eyeballed at between 6.6 cm and 6.7 cm.
