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) ≈ 3.4446083817297E-5 earth radius | 4 cable length (US) ≈ 0.00013778433526919 earth radius |
| 1.5 cable length (US) ≈ 5.1669125725946E-5 earth radius | 4.5 cable length (US) ≈ 0.00015500737717784 earth radius |
| 2 cable length (US) ≈ 6.8892167634594E-5 earth radius | 5 cable length (US) ≈ 0.00017223041908649 earth radius |
| 2.5 cable length (US) ≈ 8.6115209543243E-5 earth radius | 5.5 cable length (US) ≈ 0.00018945346099513 earth radius |
| 3 cable length (US) ≈ 0.00010333825145189 earth radius | 6 cable length (US) ≈ 0.00020667650290378 earth radius |
Earth radius is the distance from Earth's center to its surface, about 6,371 km (3,959 mi). This length is also used as a unit of distance, especially in astronomy and geology, where it is usually denoted by R⊕.
