    A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). ). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or

    [7] He notes that these notes, when sounded in succession, form the scale of the instrument, and an interval between any two notes is measured by "the ratio of the smaller pitch number to the larger, or by the fraction formed by dividing the larger by the smaller". [8] Absolute and relative pitches were also defined based on these ratios. [8]

    The physical group size equivalent to m minutes of arc can be calculated as follows: group size = tan(⁠ m / 60 ⁠) × distance. In the example previously given, for 1 minute of arc, and substituting 3,600 inches for 100 yards, 3,600 tan(⁠ 1 / 60 ⁠) ≈ 1.047 inches. In metric units 1 MOA at 100 metres ≈ 2.908 centimetres.

[9] Slovakia has the lowest Gini coefficient, with a Gini coefficient of 0.232. [10] Various sources have estimated the Gini coefficient of the global income in 2005 to be between 0.61 and 0.68.
