The H0m gauge is designed for the reproduction of narrow gauge railways with a prototype gauge of 850 to 1250 mm in H0 scale. The letter m stands for metre prototype gauge with a track width of 1000 mm. It runs on 12 mm (0.472 in) TT scale tracks.
This is a list of firearm cartridges which have bullets in the 12 millimetres (0.47 in) to 12.99 millimetres (0.511 in) caliber range.. Length refers to the cartridge case length.
H0m, 1:87 scale with rails 12 mm apart, representing metre gauge; 00n3, 1:76 scale with rails 12 mm apart, representing 3-foot gauge; 5.5 mm scale, 1:55 scale with rails 12 mm apart, representing narrow gauge; On2 gauge, 1:48 scale with rails 12.7 mm apart, representing narrow gauge
The terametre (SI symbol: Tm) is a unit of length in the metric system equal to 1 000 000 000 000 meters (10 12 m). To help compare different distances, this section lists lengths starting at 10 12 m (1 Tm or 1 billion km or 6.7 astronomical units). ≈1 Tm – 6.7 au – diameter of the red supergiant Betelgeuse based on multiple angular ...
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
The Vickers .5 inch machine gun (officially "Gun, Machine, Vickers, .5-in") also known as the Vickers .50 was a large-calibre British automatic weapon. The gun was commonly used as a close-in anti-aircraft weapon on Royal Navy and Allied ships, typically in a four-gun mounting (UK) or two-gun mounting (Dutch), as well as tanks and other armoured fighting vehicles.
In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...
The 12.7 × 108 mm has 22.72 ml (350 grains) H 2 O cartridge case capacity. 12.7 × 108 mm maximum cartridge dimensions. [citation needed] All sizes in millimeters (mm). Americans define the shoulder angle at alpha/2 ≈ 18.16 degrees. According to guidelines the 12.7 × 108 mm case can handle up to 360 MPa (52,213 psi) piezo pressure.
