The accuracy of fire at 300 m (328 yd) (R 50) is stated as 75 mm (3.0 in), at 600 m (656 yd) (R 50) is stated as 140 mm (5.5 in) and at 800 m (875 yd) (R 50) is stated as 230 mm (9.1 in). R 50 at a specific range means the closest 50 percent of the shot group will all be within a circle of the mentioned diameter at that range.
A thousandth of an inch is a derived unit of length in a system of units using inches.Equal to 1 ⁄ 1000 of an inch, a thousandth is commonly called a thou / ˈ θ aʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils).
is the diameter of the particle or grain in millimeters (Krumbein and Monk's equation) [2] and D 0 {\displaystyle D_{0}} is a reference diameter, equal to 1 mm (to make the equation dimensionally consistent ).
One millimetre of mercury is approximately 1 torr, which is 1 / 760 of standard atmospheric pressure ( 101 325 / 760 ≈ 133.322 368 421 pascals). Although the two units are not equal, the relative difference (less than 0.000 015% ) is negligible for most practical uses.

While Executive refers to 7 + 1 ⁄ 4 in × 10 + 1 ⁄ 2 in (185 mm × 265 mm) in America, the Japanese organization for standardization specified it as 216 mm × 330 mm (8.5 in × 13.0 in), which is elsewhere known as Government Legal or Foolscap.
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol ′, is a unit of angular measurement equal to 1 / 60 of one degree. [1] Since one degree is 1 / 360 of a turn, or complete rotation, one arcminute is 1 / 21 600 of a turn.
The United States retained the 1 / 39.37 -metre definition for surveying, producing a 2 millionth part difference between standard and US survey inches. [47] This is approximately 1 / 8 inch per mile; 12.7 kilometres is exactly 500,000 standard inches and exactly 499,999 survey inches.
