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) = 960 spans | 4 cable length (US) = 3840 spans |
| 1.5 cable length (US) = 1440 spans | 4.5 cable length (US) = 4320 spans |
| 2 cable length (US) = 1920 spans | 5 cable length (US) = 4800 spans |
| 2.5 cable length (US) = 2400 spans | 5.5 cable length (US) = 5280 spans |
| 3 cable length (US) = 2880 spans | 6 cable length (US) = 5760 spans |
A span is the distance measured by a human hand, from the tip of the thumb to the tip of the little finger. In ancient times, a span was considered to be half a cubit. Sometimes the distinction is made between the great span (thumb to little finger) and little span (index finger to little finger).
| 1 spans = 0.0010416666666667 cable length (US) | 4 spans = 0.0041666666666667 cable length (US) |
| 1.5 spans = 0.0015625 cable length (US) | 4.5 spans = 0.0046875 cable length (US) |
| 2 spans = 0.0020833333333333 cable length (US) | 5 spans = 0.0052083333333333 cable length (US) |
| 2.5 spans = 0.0026041666666667 cable length (US) | 5.5 spans = 0.0057291666666667 cable length (US) |
