However, welcome news regarding Scottâs future came early in 1919 with the War Departmentâs decision to purchase Scott Field. Scottâs central location and the exceptional price of $119,285.84 influenced this decision and set the stage for Scott Air Force Baseâs amazing military future. In 1920, the government decided that the field should be turned over to the lighter-than-air branch of the Air Corps.
40075.02 / 360 / 60 = 1.8553 km. One minute of longitude on equator is 1.8553 km. Please note - on equator (i.e. on 0 degree of latitude)! Because the length of parallels decrease toward the north or south pole, the length (in km or miles) of minute of longitude differs for different latitudes.
Latitude and longitude are both measured in degrees. Each degree (Â°) is subdivided into 60 minutes (') and each minute into 60 seconds (). Each degree of latitude corresponds to a distance on the Earthâs surface of about 111 km.Each degree of longitude however, corresponds to a distance that varies with latitude. The distance is about 111 km at the Equator, reducing to 0 km at the Poles.henever the unqualified term latitude is used, it will normally mean the geographic latitude. On the WGS84 ellipsoid, the length of a degree of latitude increases from 110.574 km at the equator to 111.694 km at the poles.
