Scale for RC model ships, usually produced by Dumas: 1:36: 8.467 mm Popular scale for period ship plans — 1 inch = 3 feet. 1:35: 8.709 mm: Military models: The most popular scale for military vehicles and figures. Used heavily in models of armoured vehicles. It was originally conceived by Tamiya for convenience of fitting motorised parts and ...
For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200 ⁄ 3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0.9144 ...
2 mm scale, often 2 mm finescale is a specification used for railway modelling, [1] largely for modelling British railway prototypes. [citation needed] It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. [1] The track gauge used to represent prototype standard gauge (4 feet 8 + 1 ⁄ 2 inches) is 9.42 mm ...
The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in). The Greek foot (πούς, pous) had a length of 1 / 600 of a stadion, [12] one stadion being about 181.2 m (594 ft); [13] therefore a foot was, at the time, about 302 mm (11.9 in). Its ...
The other units of length and mass, and all units of area, volume, and derived units such as density were derived from these two base units. Mesures usuelles (French for customary measures) were a system of measurement introduced as a compromise between the metric system and traditional measurements. It was used in France from 1812 to 1839.
From fingertips to elbow, 18 inches. Yard: 0.914 m: 3 feet = 36 inches, the practical base unit, defined as the length of the prototype bar held by the Crown or Exchequer. Ell: 1.143 m: From fingertip of outstretched arm to opposite shoulder, 20 nails = 1 + 1 ⁄ 4 yard or 45 inches. Mostly for measuring cloth. Fathom: 1.829 m
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
