the US system is metric based, with an inch being defined as 2.54cm exactly.
That is not true for a survey inch.

It's very Pythonesque -- what do you mean, Commonwealth or Mendenhall?
Correct. That's the problem when you have multiple things overloading a
term. You get things like international inch, surveyer's inch (which
differs by 2ppm) and all the approximate things we used back before
things were standardized.
Hmmm, isn't that just what we're talking about with the overloaded term
second?
