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:
| Name of unit | Symbol | Definition | Relation to SI units | Unit System |
|---|---|---|---|---|
| cable length (imperial) | ≡ 608 ft | ≈ 185.3184 m | Imperial/US |
| cable length (imperial) | metric inches | cable length (imperial) | metric inches |
|---|---|---|---|
| 1 | ≈ 463296 | 4 | ≈ 1853184 |
| 1.5 | ≈ 694944 | 4.5 | ≈ 2084832 |
| 2 | ≈ 926592 | 5 | ≈ 2316480 |
| 2.5 | ≈ 1158240 | 5.5 | ≈ 2548128 |
| 3 | ≈ 1389888 | 6 | ≈ 2779776 |
A metric inch is a nickname for a preferred 1⁄4 subdivision of an ISO 2848 basic module, or 1⁄12 of a metric foot measuring 25 millimetres (0.984 in). A metric inch is 0.4 millimetres (0.016 in) shorter than an inch.
The term was similarly used to refer to the historical Soviet Bloc practice of spacing integrated circuit pins at 1⁄10 of a 25 mm "metric inch" length, instead of the western practice of 1⁄10 of an imperial inch.
