This is the scale which MOROP has defined for O scale, because it is half the size of the 1:22.5 Scale G-gauge model railways made by German manufacturers. [citation needed] 1:43.5: 7.02 mm: Model railways (0) Exact O scale of 7 mm = 1 foot. 1:43: 7.088 mm: Die-cast cars: Still the most popular scale for die-cast cars worldwide, metric or ...
Narrow-gauge models in this gauge can be as large as 1:3 scale. 5-inch Live steam: 1:12: 127 mm or 121 mm Ridable, outdoor gauge. The gauge is 5 in (127 mm) in Europe, but 4 + 3 ⁄ 4 in (121 mm) in US and Canada. For standard gauge prototypes at 5 inch, the correct scale is 1 1 ⁄ 16 inch per foot or approximately 1:11.3. Alternatively 1.1/8 ...
From 1920, the standard gauge part of the Siam railway amounting to 1,000 km (620 mi) was converted first to third rail, and then to 1,000 mm (3 ft 3 + 3 ⁄ 8 in) (metre gauge) making the whole system metre gauge. [19] 1,435 mm (4 ft 8 + 1 ⁄ 2 in) 1,000 mm (3 ft 3 + 3 ⁄ 8 in) (proposed) Tunisia: Tunis - Sfax Line 1,435 mm (4 ft 8 + 1 ⁄ 2 in)
The prefix kilo, for example, implies a factor of 1000 (10 3), and the prefix milli implies a factor of 1/1000 (10-3). Thus, a kilometre is a thousand metres, and a milligram is one thousandth of a gram. These relations can be written symbolically as: [4]
The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or 1 / 100 . A bar scale would also normally appear on the drawing.
The solar flux unit is a unit of spectral irradiance equal to 10 −22 W⋅m −2 ⋅Hz −1 (100 yW⋅m −2 ⋅Hz −1). The nox (nx) is a unit of illuminance equal to 1 millilux (1 mlx). The nit (nt) is a unit of luminance equal to one candela per metre squared (1 cd⋅m −2). The lambert (L) is a unit of luminance equal to 10 4 /π cd⋅m ...
The most common units in modern use are the metric units, used in every country globally. In the United States the U.S. customary units are also in use. British Imperial units are still used for some purposes in the United Kingdom and some other countries. The metric system is sub-divided into SI and non-SI units. [1] [2] [3]
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
