A mile is exactly 1000 paces, or 4000 feet. You may disagree, but consider: the word mile come from latin for "one thousand". Therefore a mile must be 1000 of something, namely paces. I hope you find this argument convincing.

There is a "metric mile" which is 1500 m. This is something in the context of track and field athletics.

There is also a "metric gallon", or 4L.
