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 (International) ≡ 1.852E+17 fermtometers | 4 cable length (International) ≡ 7.408E+17 fermtometers |
| 1.5 cable length (International) ≡ 2.778E+17 fermtometers | 4.5 cable length (International) ≡ 8.334E+17 fermtometers |
| 2 cable length (International) ≡ 3.704E+17 fermtometers | 5 cable length (International) ≡ 9.26E+17 fermtometers |
| 2.5 cable length (International) ≡ 4.63E+17 fermtometers | 5.5 cable length (International) ≡ 1.0186E+18 fermtometers |
| 3 cable length (International) ≡ 5.556E+17 fermtometers | 6 cable length (International) ≡ 1.1112E+18 fermtometers |
The femtometre (American spelling femtometer, symbol fm derived from the Danish and Norwegian word femten, "fifteen"+Ancient Greek: μέτρον, metrοn, "unit of measurement") is an SI unit of length equal to 10−15 metres, which means a quadrillionth of one. This distance can also be called a fermi and was so named in honour of physicist Enrico Fermi, as it is a typical length-scale of nuclear physics.
