Ship models: This was a standard size for ship models produced by Revell and Italeri but they have moved from it. 1:700: 0.435 mm: Ship models: This is the scale that most manufacturer chose to produce the largest series of waterline plastic model ships and submarines. Full hull models are popular in that scale as well. 1:600: 0.508 mm: Ship models
A scale model of a hydropower turbine. A scale model is a physical model that is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles.
Both models can be described as 15 mm, but the real world sizes depend on the size of the reference humanoid. In practice, the reference humanoid is generally assumed to be the idea of the average height of the human male, within a 6-inch (15 cm) interval between 5.5 and 6 feet (168 and 183 cm), unless otherwise indicated by the designer.
Scale (ratio) The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model ...
1,435 mm (4 ft 8 + 1⁄2 in) standard gauge. O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling. Introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s.
Structural similarity index measure. The structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. It is also used for measuring the similarity between two images. The SSIM index is a full reference metric; in ...
Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in) e = narrow gauge (650–850 mm ...
A system of units of measurement, also known as a system of units or system of measurement, is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Instances in use include the International System of ...
