3 mm scale, also known as 3 mm finescale, is a model railway scale of 3 mm : 1 ft (305 mm) used for British prototypes. Introduced as British TT gauge , it sits approximately halfway between British N gauge and OO gauge but is not as popular as either and there is no longer any mass manufacturer ready-to-run support.
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 otherwise. It originates from British O scale. 1:40: 0.3 in: 7.620 mm The very early models of the British Coronation Coach and a few other horse-drawn wagons were made in this scale.
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [ 2 ] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2 , 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4 ...

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 ...

7 mm scale, also known as British O scale is a model railway scale of 1:43.5 (or 7 mm to 1 ft; hence its name). [1] The scale is thus different from American O scale (1:48) [ 1 ] and European O scale (1:45).
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
