Two Technology Alternatives The metre was originally defined as 1⁄10,000,000 of the length of the meridian arc from the North pole to the equator, thus one kilometre of distance corresponds to one centigrad (also known as centesimal arc minute) of latitude. The Earth's circumference is therefore approximately 40,000 km. The equatorial circumference is slightly longer than the polar circumference – the measurement based on this (40,075.017 km/360 × 60 = 1,855.3 metres) is known as the geographical mile. dod charleston sc
