No conflict between the definitions existed in practice, [citation needed] since depths on imperial nautical charts were indicated in feet if less than 30 feet (9.1 m) and in fathoms for depths greater than that. Until the 19th century in England, the length of the fathom was more variable: from 5 + 1 ⁄ 2 feet on merchant vessels to either 5 ...

A cable's length (often "cable length" or just "cable") is simply the standard length in which cables came, which by 1555 had settled to around 100 fathoms (600 ft; 180 m) or 1 ⁄ 10 nautical mile (0.19 km; 0.12 mi). [1] Traditionally rope is made on long ropewalks, the length of which determines the maximum length of rope it is possible to make.
