The UK statute chain is 22 yards, which is 66 feet (20.1168 m). This unit is a statute measure in the United Kingdom, defined in the Weights and Measures Act 1985. [6] One link is a hundredth part of a chain, which is 7.92 inches (20.1168 cm).
Gunter's chain (also known as Gunter's measurement) is a distance-measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626).
Even though the gauge system was originally meant for wire, it is now used regardless of whether an item of body jewelry is an actual wire, or is instead a wooden plug, a plastic ring, or any other material. The alternative to using the gauge-and-inches system is to specify the thickness in millimeters.
The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
Left-handed and right-handed teeth are alternated in the chain. Chains are made in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets (e.g., 8 mm, 0.325 inch), while the gauge is the thickness of the drive link where it fits into the guide bar (e.g., 1.5 mm, 0.05 inch).
For example: 2-gauge wire is large (like a pencil) and 30-gauge wire is fine, like thread. In much of the world wire diameter is often expressed in millimeters. For making jump rings, 10- to 18-gauge wire (2.5 to 1.3 mm) is used. Bracelet and necklace wire components are generally made out of wire that is 16-, 18- or 20-gauge (1.3 to 0.8 mm).
The chain's disaster preparedness measures include assembling and training "Waffle House jump teams" to facilitate fast reopening after disasters. [8] Waffle House, along with other chains (such as Home Depot , Walmart , and Lowe's ) which do a significant proportion of their business in the southern US where there is a frequent risk of ...
