For example, a 7/8 violin has a scale of about 317 mm, a 3/4-size instrument a scale of 307 mm, a half-size one 287 mm, and a quarter-size one 267 mm. 1/8, 1/10, 1/16 and 1/32 and even 1/64 violins also exist, becoming progressively smaller, but again in no proportional relationship. (A full-size instrument is described as 4/4.)
T scale, using 3 mm gauge track to represent standard gauge railways. 1:450. 0.677 mm. Model railways (T) T scale, using 3 mm gauge track to represent 3 ft 6 in ( 1,067 mm) gauge railways. Hasegawa also produces plastic ship models in this scale. 1:432.
The French scale, French gauge or Charrière system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply gauge, G or GA generally refers to Birmingham gauge.
This is further complicated by the fact some scales use several different gauges; for example, HO scale uses 16.5 mm as the standard gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm), 12 mm to represent 1,000 mm (3 ft 3 + 3 ⁄ 8 in) gauge (HOm), and 3 ft 6 in (1,067 mm) (HOn3-1/2), and 9 mm to represent a prototype gauge of 2 ft (610 mm).
The recent formula used by the Brannock device assumes a foot length of 2 barleycorns less than the length of the last; thus, men's size 1 is equivalent to a last's length of 8 + 1 ⁄ 3 in (21.17 cm) and foot's length of 7 + 2 ⁄ 3 in (19.47 cm), and children's size 1 is equivalent to 4 + 1 ⁄ 4 in (10.8 cm) last's length and 3 + 7 ⁄ 12 in ...

1:18 scale is a traditional scale (ratio) for models and miniatures, in which 18 units (such as inches or centimeters) on the original is represented by one unit on the model. Depending on application, the scale is also called two third inch scale since 1 foot is represented by 2/3 of an inch. [ 1] The scale is used for 1:18 scale diecast ...
In SI units, the values of c, h, e and k B are exact and the values of ε 0 and G in SI units respectively have relative uncertainties of 1.6 × 10 −10 [16] and 2.2 × 10 −5. [17] Hence, the uncertainties in the SI values of the Planck units derive almost entirely from uncertainty in the SI value of G.
