Since this 3200 m split was en route to two miles, it is not eligible to be an NFHS 3200 metre record. If indoor tracks are considered, Mary Cain's 2013 9:38.68 two mile time converts down to a 9:35.32 3200 m, and is the therefore the fastest 3200 m split ever recorded for a high school girl.
In the United States, the term statute mile formally refers to the survey mile, [3] but for most purposes, the difference of less than 1 ⁄ 8 inch (3.2 mm) between the survey mile and the international mile (1609.344 metres exactly) is insignificant—one international mile is 0.999 998 US survey miles—so statute mile can be used

Like the mile run, it is still contested at some invitational meets due its historical chronology in the United States and United Kingdom. It has been largely superseded by the 3000 m (approximately 1.864 miles) and 5000 m , and by the 3200 m in NFHS American high school competitions (18.688m short of 2 miles).
The length of the internationally agreed nautical mile is 1 852 m. The US adopted the international definition in 1954, having previously used the US nautical mile ( 1 853 .248 m ). [ 6 ] The UK adopted the international nautical mile definition in 1970, having previously used the UK Admiralty nautical mile ( 6 080 ft or 1 853 .184 m ).
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
