The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.
This gauge is represented by the EM Society (in full, Eighteen Millimetre Society). 00 track (16.5 mm) is the wrong gauge for 1:76 scale, but use of an 18.2 mm (0.717 in) gauge track is accepted as the most popular compromise towards scale dimensions without having to make significant modifications to ready-to-run models. Has a track gauge ...
H0 scale using 3-scale-foot narrow-gauge track. HOe gauge: 1:87: 9 mm European HO scale narrow-gauge models using 9 mm (0.354 in) (the same as N scale) track to represent prototypes with gauge between 650 and 850 mm (25.6 and 33.5 in), particularly 750 mm (2 ft 5 + 1 ⁄ 2 in) and 760 mm (2 ft 5 + 15 ⁄ 16 in) gauge. HOn2 gauge: 1:87: 7 mm
Broad gauge is being converted to dual gauge by installing narrow gauge third rail. 762 mm (2 ft 6 in) 1,067 mm (3 ft 6 in) 1898 Barbados: Barbados Railway: 1,435 mm (4 ft 8 + 1 ⁄ 2 in) 1,676 mm (5 ft 6 in) 1880s Canada: Numerous Provincial Gauge railways in Canada 1,435 mm (4 ft 8 + 1 ⁄ 2 in) 1,067 mm (3 ft 6 in) 1881 Canada
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 ...
The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm). The increments between gauge sizes are not linear and vary. [2] At higher gauge numbers, the increment between the two ...
The M/88 bore originally had 7.90 mm (0.311 in) lands diameter and 8.10 mm (0.319 in) grooves diameter. The M/88 barrel bore specification was changed by 1894–1895 to 7.90 mm (0.311 in) lands diameter and 8.20 mm (0.323 in) grooves diameter to improve accuracy and reduce barrel wear in M/88 chambered arms.
