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 ...
And conversely, the group size of 1 milliradian at 100 meters (the default metric sighting-in distance) can be determined just as easily: 1 milliradian at 100 meters distance = 100 millimeters = 10 centimeters {\displaystyle {\text{1 milliradian at 100 meters distance}}={\text{100 millimeters}}={\text{10 centimeters}}}
An object 5 meters high, for example, will cover 1 mrad at 5000 meters, or 5 mrad at 1000 meters, or 25 mrad at 200 meters. ... 28" × 1 milliradian ≈ 0.028" (0.071 ...

Sergey Bubka's 1993 pole vault world indoor record of 6.15 m was not considered to be a world record, because it was set before the new rule came into effect. Bubka's world record of 6.14 m, set outdoors in 1994, was surpassed by six consecutive records set indoors, most recently by Armand Duplantis in 2023 with a 6.22 m mark. In 2020 ...
