The survey mile (or U.S. statute mile) is a common measurement in the U.S. where the mile is defined based on the survey foot. This results a slightly different calculation than the statute mile, which is defined as exactly 1609.344 meters. The survey mile is defined as 5280 survey feet, which comes out to around 1609.3472 meters.

››Definition: Light-day

A light day (also written light-day) is a unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 metres (~26 Tm).

Note that this value is exact, since the metre is actually defined in terms of the speed of light. The light day isn't very frequently used at all since there are few astronomical objects or distances of that magnitude; the Oort cloud, for example, is thought to extend between 290 and 580 light-days out from the Sun.
