Geographical mile longitude at the equator is thus exactly 60 geographical miles. It was closely related to the nautical mile, which was originally determined as 1 minute of arc along a great circle of the Earth, but is nowadays defined as exactly 1852 metres. The US National Institute of Standards and Technology (NIST) notes that: "The international nautical mile of 1 852 meters (6 076.115 49...feet) was adopted effective July 1, 1954, for use in the United States. The value formerly used in the United States was 6 080.20 feet = 1 nautical (geographical or sea) mile." (6080.2 feet is 1853.24496 meters.)
Libyan units of measurement Libyan units of measurement A number of different units of measurement were used in Libya to measure length, mass, area, etc. Metric system adopted in Libya in 1927. A number of different units were used. Several units were used to measure length. One pik was equal to 0.68 m as it was defined by metric equivalent. Some other units are given below (Note: these units too were defined by metric equivalents): 1 handaze = 1 pik 1 palmo = 1/3 pik 1 draa = 0.46 m. In tripoli, draa was equal to 26.42 in and arbi draa (lesser pik) was
