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.
By combining longitude and latitude measurements, any location on earth can be determined. The units of measurement for geographic coordinates are degrees (Â°), minutes ('), and seconds (). Like a circle, the Earth has 360 degrees. Each degree is divided into 60 minutes, which in turn is divided into 60 seconds. Latitude and longitude coordinates also include cardinal directions: north or south of the equator for latitude, and east or west of the prime meridian for longitude.
