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:

A twip (abbreviating "twentieth of a point", "twentieth of an inch point", or "twentieth of an Imperial point"[citation needed]) is a typographical measurement, defined as 1/20 of a typographical point. One twip is 1/1440 inch or 17.639 µm.
