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] The French units roughly correspond to the outer circumference of the catheter (see table below).
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.
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.
Sizes that may interchange, depending on the precision needed, include 2 mm (close to 5 ⁄ 64 inch (1.98 mm)), 4 mm (close to 5 ⁄ 32 inch (3.97 mm)) and 8 mm (close to 5 ⁄ 16 inch (7.94 mm)). In reality, a wrench with a width across the flats of exactly 15 mm would fit too tightly to use on a bolt with a width across the flats of 15 mm.
Metric drill bit sizes. Metric drill set, 1.0–6.0 mm by 0.1 mm, jobber length. The case that holds them in an indexed order (by size), via a graduated series of holes, is called a drill index. Metric drill bit sizes define the diameter of the bit in terms of standard metric lengths. Standards organizations define sets of sizes that are ...
30 mph (54.7 km/h) The 8-inch (203 mm) M110 self-propelled howitzer is an American self-propelled artillery system consisting of an M115 203 mm howitzer installed on a purpose-built chassis. Before its retirement from US service, it was the largest available self-propelled howitzer in the United States Army 's inventory; it continues in service ...
25.4 μm. A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to 1000 of an inch, a thousandth is commonly called a thou / ˈθaʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils ). The words are shortened forms of the English and Latin words for "thousand ...
5.75 in × 3.25 in × 8 in (146.1 mm × 82.55 mm × 203 mm). This smaller form factor, first used in an HDD by Seagate in 1980, was the same size as full-height 51⁄4 -inch-diameter (130 mm) FDD, 3.25-inches high. This is twice as high as "half height"; i.e., 1.63 in (41.4 mm). Most desktop models of drives for optical 120 mm disks (DVD, CD ...
