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.
[7] [8] However, this figure drops to 0.52 after social assistance is taken into account and drops again to 0.47 after taxation. [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.

The Babylonians were aware that this was an approximation, and one Old Babylonian mathematical tablet excavated near Susa in 1936 (dated to between the 19th and 17th centuries BCE) gives a better approximation of π as 25 ⁄ 8 = 3.125, about 0.528% below the exact value. [8] [9] [10] [11]
It equals 6°, so a whole turn was divided into 60 hexacontades. pechus: 144 to 180: 2° to 2°30′ The pechus was a Babylonian unit equal to about 2° or 2 + 1 / 2 °. diameter part: ≈376.991: ≈0.95493° The diameter part (occasionally used in Islamic mathematics) is 1 / 60 radian. One "diameter part" is approximately 0. ...
The notation 8 a or 8 va is sometimes seen in sheet music, meaning "play this an octave higher than written" (all' ottava: "at the octave" or all' 8 va). 8 a or 8 va stands for ottava , the Italian word for octave (or "eighth"); the octave above may be specified as ottava alta or ottava sopra ).
