We use 0.25 statute mile in US

Question:

What is a US Statute Mile in terms of feet or metres?

It's defined as 5280 "survey feet", and the survey foot is in turn defined
as 1200/3937 meters.

The term "Mile" is ambiguous. There are lots of different "miles",
for instance there are theoretically an infinite number
of different lengths of Nautical Mile ....

But only one definition of a Metre, and therefore a Kilometre.

The statute mile may be weird and inconvenient, but it's no more imprecise
than the kilometer.
