DISTANCE information:
* NM = Nautical Miles : Universally used for flight distances.
* SM = Statute Miles : Used in the USA for visibility information in weather reports.
* ft = feet : Mainly used for altitudes and heights, also used for lenght and width (runways, aprons, taxiways) in anglo-saxon countries.
* m = meters :Used for length and width (runways, aprons, taxiways) everywhere except in anglo-saxon countries. Sometimes used for altitudes (gliders, helicopters). Used also in weather reports for visibility.

Altimeter (hPa & MM to InHg)
The altimeter setting is being displayed in hectopascals (hPa, 1 hPa =1 mb) or mercury inches (inHg in anglo-saxon countries).
The standard setting is 1013.25 hPa = 29.92 inHg.
