Exact HO scale (half O of 7 mm = 1 foot) 1:87: 3.503 mm: Model railways (HO/h0) Civilian and military vehicles. Often used to describe HO scale. Original nominal 25 mm figure scale; though a 6-foot human in 1:87 is closer to 21 mm. 1:82: 3.717 mm An intermediate scale (HO/OO) intended to apply to both HO and OO scale train sets.
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 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 ...
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.

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.
