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. The unit is named after the length of a ship's anchor cable in the Age of Sail. The definition varies:
| 1 cable length (US) = 120 fathoms | 4 cable length (US) = 480 fathoms |
| 1.5 cable length (US) = 180 fathoms | 4.5 cable length (US) = 540 fathoms |
| 2 cable length (US) = 240 fathoms | 5 cable length (US) = 600 fathoms |
| 2.5 cable length (US) = 300 fathoms | 5.5 cable length (US) = 660 fathoms |
| 3 cable length (US) = 360 fathoms | 6 cable length (US) = 720 fathoms |
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 metres), used especially for measuring the depth of water.
There are two yards (6 feet) in an imperial fathom. Originally the span of a man's outstretched arms, the size of a fathom has varied slightly depending on whether it was defined as a thousandth of an (Admiralty) nautical mile or as a multiple of the imperial yard. Formerly, the term was used for any of several units of length varying around 5–5 1⁄2 feet.
