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.

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) = 2.19456E+17 fermtometers | 4 cable length (US) = 8.77824E+17 fermtometers |
| 1.5 cable length (US) = 3.29184E+17 fermtometers | 4.5 cable length (US) = 9.87552E+17 fermtometers |
| 2 cable length (US) = 4.38912E+17 fermtometers | 5 cable length (US) = 1.09728E+18 fermtometers |
| 2.5 cable length (US) = 5.4864E+17 fermtometers | 5.5 cable length (US) = 1.207008E+18 fermtometers |
| 3 cable length (US) = 6.58368E+17 fermtometers | 6 cable length (US) = 1.316736E+18 fermtometers |
| 1 fermtometers = 4.5567220764071 × 10-18 cable length (US) |
