A common adjustment value in firearm sights is 1 cm at 100 meters which equals 10 mm / 100 m = 1 / 10 mrad. The true definition of a milliradian is based on a unit circle with a radius of one and an arc divided into 1,000 mrad per radian, hence 2,000 π or approximately 6,283.185 milliradians in one turn , and rifle scope ...
The group on the right measures about 7 mm and was fired at about 90 meters, which equals 7 mm / 90 m = 0.08 mils (0.3 in group at 100 yards, approx. 1.047′×0.3 = 0.314′). In shooting sports , a shot grouping , or simply group , is the collective pattern of projectile impacts on a target from multiple consecutive shots taken in one ...
The subtension is linear with the distance, for example, at 500 yards, 1 MOA subtends 5.235 inches, and at 1000 yards 1 MOA subtends 10.47 inches. Since many modern telescopic sights are adjustable in half ( 1 / 2 ), quarter ( 1 / 4 ) or eighth ( 1 / 8 ) MOA increments, also known as clicks , zeroing and adjustments are ...
This can be expressed in linear measures (a 30 mm group at 100 m, or a one inch group at 100 yards) or in angular measures (a milliradian or MOA group). Groups for rifles are traditionally shot at either 100 meters or 100 yards (91 m).
Stadiametric rangefinding often uses the milliradian ("mil" or "mrad") as the unit of angular measurement. Since a radian is defined as the angle formed when the length of a circular arc equals the radius of the circle, a milliradian is the angle formed when the length of a circular arc equals 1/1000 of the radius of the circle.

The USMC standard is that 1 mil (that is, 1 milliradian) equals 3.438 MOA (minute of arc, or, equivalently, minute of angle), while the US Army standard is 3.6 MOA, chosen so as to give a diameter of 1 yard at a distance of 1,000 yards (or equivalently, a diameter of 1 meter at a range of 1 kilometer.) Many commercial manufacturers use 3.5 ...
