Arabic mile

Historical unit of length used by Arabs

The Arab, Arabic, or Arabian mile was a historical Arabic unit of length. Its precise length is disputed, lying between 1,800 metres (5,900 ft) and 2,000 metres (6,600 ft). It was used by medieval Arab geographers and astronomers. The predecessor of the modern nautical mile, it extended the Roman mile to fit an astronomical approximation of 1 minute of an arc of latitude measured along a north–south meridian. The distance between two pillars whose latitudes differed by 1 degree in a north–south direction was measured using sighting pegs along a flat desert plane.
