However, simply gauge, G or GA generally refers to Birmingham gauge. [1] The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3. [2]
However, the 3 + 1 ⁄ 2-inch (89 mm) 12-gauge shell, with its higher SAAMI pressure rating of 14,000 psi (97 MPa) compared to standard 2 + 3 ⁄ 4-inch (70 mm) and 3-inch (76 mm) 12-gauge shells with their lower pressure rating of 11,500 psi (79 MPa), began to approach the performance of the 3 + 1 ⁄ 2-inch (89 mm) 10-gauge shells with a ...
1 gauge, gauge 1 or gauge one is a model railway and toy train standard that was popular in the early 20th century, particularly with European manufacturers. Its track measures 1.75 in (44.45 mm), making it larger than 0 gauge but slightly smaller than wide gauge, which came to be the dominant U.S. standard during the 1920s.
Same as Gauge 1, cars, common for slot cars. Commonly referred to as Stablemate size in model horses. 1:30.5: 10 mm Often quoted as the alternative to 1:32 scale. 1:30: 0.4 in: 10.16 mm Toy soldiers and military vehicles including King & Country and Figarti. 1:29: 10.51 mm American model trains running on 45 mm Gauge 1 track. 1:28: 10.89 mm
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. The first attempt to adopt a geometrical system was made by Messrs Brown & Sharpe in 1855.
Shotguns are classed according to gauge, a related expression. The gauge of a shotgun refers to how many lead spheres, each with a diameter equal to that of the bore, that amounts to one pound (454 g (1.0 lb)) in weight. In the case of a 12-gauge (18.5 mm) shotgun, it would take 12 spheres the size of the shotgun's bore to equal a pound. [12]
Sulitjelma Line converted from 750 mm (2 ft 5 + 1 ⁄ 2 in) to dual gauge with 1,067 mm (3 ft 6 in) and when later closed was converted to a road. 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) 1,067 mm ( 3 ft 6 in )
Gauge block, a metal or ceramic block of precisely known dimension, used in measuring; Sight glass, also known as a water gauge, for measuring liquid level heights in storage tanks and pressure vessels; Boost gauge, a gauge used in conjunction with turbo-super-chargers; Pressure gauge or vacuum gauge, see pressure measurement
