A tuck seine or tuck net about 70 fathoms (420 ft; 130 m) long, and very deep in the middle, was used to take fish from a larger seine. A line attached to a whaling harpoon was about 150 fathoms (900 ft; 270 m). A forerunner — a piece of cloth tied on a ship's log line some fathoms from the outboard end — marked the limit of drift line. [25]

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.
The imperial nautical mile of 6080 feet (1853.19 m) was also formerly used by the Japanese in maritime contexts as a "marine ri". [14] A fourth and shorter ri of about 600 m is still evident in some beach names. The "99-Ri" beach at Kujukuri is about 60 km. The "7-Ri" beach at Shichiri is 4.2 km long.
In Paris, the redefinition in terms of metric units made 1 m = 443.296 ligne = 3 pied 11.296 ligne. In Quebec, the surveys in French units were converted using the relationship 1 pied (of the French variety; the same word is used for English feet as well) = 12.789 inches (of English origin).
Normal weight is the same as healthy weight in the report. But BMI is a controversial measurement of health, given that it only looks at height and weight — not different elements like body fat ...
The American football field, which has a playing area 100 yards (91.4 m) long by 160 feet (48.8 m) wide. This is often used by the American public media for the sizes of large buildings or parks. It is used both as a unit of length (100 yd or 91.4 m, the length of the playing field excluding goal areas) and as a unit of area (57,600 sq ft or ...
A sailor and a man on shore, both sounding the depth with a line. Depth sounding, often simply called sounding, is measuring the depth of a body of water.Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography.
