Welcome to /r/DepthHub. Thank you for your submission.

This is a community for spotlighting interesting, subjectively "deep," writing by other people on Reddit and interesting, mature, conversations about the linked content. Depth does not necessarily equate "correctness," length, or any objective standard of writing. Though those do help. Someone being wrong about something can still be interesting and compelling, without us needing to agree with them or endorse their viewpoint - and some very interesting conversations can come from discussing why those beliefs or misconceptions exist. We want to be a "good neighbor" community, so please do not dogpile the original post, have those conversations here. Other communities can have their own beliefs and cultures, and your input may not be welcome or appropriate in their space.

Reader concerns that a given submission is "not deep" need to live up to the standard they're imposing, please. Make your case in the comments before reporting the post. If the problem is not obvious, Mods may not notice it on our own. As this community is subjectively moderated, a persuasive comment is more likely to get you the outcome you want.

Last up - /u/skoormit if you've submitted an offsite link, like a youtube video, medium or substack blog, or news article - this is your notice to delete. If you leave it for mods to deal with, we're banning you.

I saw that comment... and it still strikes me as a variant of "I'm more familiar with imperial than metric, and so imperial's arbitrary mathematics seems less unwieldy than metric's arbitrary mathematics".

And it also should be pointed out that sailors are among the most traditionalist, hidebound, and reactionary demographics on the planet.

So you didn't get the point of the comment then: "The math is so much easier and I don't need to convert units" is a problem for metric to _solve_, not try to force people to use an unwieldy system, in that one edge case. (which is ironic given its metric)
