Also known as

An international mile is usually referred to just as a mile.

It is sometimes seen referred to as a statute mile, but this is an older term dating back to before the precise $1959$ definition based on the metre.

There are many other kinds of mile.

Historical Note

The international mile was a readjustment and redefinition in $1959$ of the statute mile.

The latter had been defined by statute in $1593$ under the reign of Queen Elizabeth I of England.

Previously there were a number of different and variously-defined miles used throughout not only the world, but also the British Isles.
