Earth's circumference mile in the seventeenth century and the metre in the eighteenth. Earth's polar circumference is almost exactly 40,000 km because the metre was originally calibrated on this measurement (1/10-millionth of the distance between the poles and the equator), which is almost exactly 21,600 nautical miles (being defined as one minute of a degree – i.e. 360 multiplied by 60). It has been described as "the single most important measurement" of the Earth, assuming the Earth to be a sphere (the Earth is an technically an ellipsoid, albeit with just 0.3% flattening). Earth's circumference lines are the foundation of the coordinate
Code page 852 Code page 852 Code page 852 (also known as CP 852, IBM 00852, OEM 852 (Latin II), MS-DOS Latin 2) is a code page used under DOS to write Central European languages that use Latin script (such as Bosnian, Croatian, Czech, Hungarian, Polish, Romanian, Serbian, Slovak or Slovene).
