What's important here is that the standard measurements evolved naturally from people doing and making things. The common lengths were so chosen because they were easy to "eyeball" for craftspeople, and they were lengths that were useful to make things in - not some arbitrary designation based on phenomenon far outside the human experience.

Maybe so for feet, how about other measurements and its conversion. Where's inch coming from and why it's 12 inch to be 1 feet, and for yards, miles etc. It's kinda arbitrary, not natural, and confusing
