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.

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.
The Earth rotates one full turn (360Âº of longitude) in one day. It therefore turns one degree of longitude in 1/360th of a day, or every four minutes. To calculate your longitude, you therefore simply need to work out the time difference between noon at your location and noon at the Prime Meridian.
