The Official Table of Drops, formerly issued by the British Home Office, is a manual which is used to calculate the appropriate length of rope for long drop hangings. Following a series of failed hangings, including those of John Babbacombe Lee , a committee chaired by Henry Bruce, 1st Baron Aberdare was formed in 1886 to discover and report on ...
The Byzantine equivalent, the schoinion or "little rope", varied between 60 and 72 Greek feet depending upon the location. The Thai sen of 20 Thai fathoms or 40 m also means and is translated "rope". The Somerset rope was a former English unit used in drainage and hedging. It was 20 feet (now precisely 6.096 m). [1] [2]
The length of these fids is typically 21 or 22 times the diameter of rope to be spliced. A one-half-inch (12.7 mm) diameter rope would have any accompanying fid 10.5–11 in (266.7–279.4 mm) in length with hash-marks denoting the long and short fid measurements. A short fid is 1 ⁄ 3 a fid length and a long fid is 2 ⁄ 3 the overall fid length.
American surveyors use a decimal-based system of measurement devised by Edmund Gunter in 1620. The base unit is Gunter's chain of 66 feet (20 m) which is subdivided into 4 rods, each of 16.5 ft or 100 links of 0.66 feet. A link is abbreviated "lk", and links "lks", in old deeds and land surveys done for the government.
NMRA standard S-1.2 covers the popular model railway scales and S-1.3 defines scales with deep flanges for model railways with very sharp curves or other garden railway specific design features. In certain NMRA scales an alternative designation is sometimes used corresponding the length of one prototype foot in scale either in millimetres or in ...

A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".
A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale.In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
