{{no footnotes|date=January 2013}}A cable length or length of cable is a nautical unit of measure equal to one tenth of a nautical mile or approximately 100 fathoms. Due to anachronisms and varying techniques of measurement, a cable length can be anywhere from 169 to 220 metres, depending on the standard used. The unit is named after the length of a ship's anchor cable in the Age of Sail. The definition varies: - International: 185.2 m, equivalent to {{frac|10}} nautical mile
- Imperial (Admiralty): 185.32 m, or {{frac|10}} Admiralty mile, about 101 fathoms
- The traditional British fathom varied from 5½ feet to 7 feet in the Merchant Navy, making the "historical" cable 169 m to 215.5 m.
- U.S. customary (US Navy): 219.5 metres, 120 fathoms (720 feet)
