A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth (1/60) of one degree. As one degree is 1/360 of a circle, one minute of arc is 1/21600 of a circle (or, in radians, π/10800). It is used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying and marksmanship.
The number of square arcminutes in a complete sphere is approximately 148,510,660 square arcminutes.
A second of arc (arcsecond, arcsec) is 1/60 of an arcminute, 1/3,600 of a degree, 1/1,296,000 of a circle, and π/648,000 (about 1/206,265) of a radian. This is approximately the angle subtended by a U.S. dime coin (18mm) at a distance of 4 kilometres (about 2.5mi).
To express even smaller angles, standard SI prefixes can be employed; the milliarcsecond (mas), for instance, is commonly used in astronomy.
Symbols and abbreviations
The standard symbol for marking the arcminute is the prime (′) (U+2032), though a single quote (') (U+0027) is commonly used where only ASCII characters are permitted. One arcminute is thus written 1′. It is also abbreviated as arcmin or amin or, less commonly, the prime with a circumflex over it ().

Description: A minute of arc, arcminute , arc minute, or minute arc is a unit of angular measurement equal to 1/60 of one degree. Since one degree is 1/360 of a turn , one minute of arc is 1/21600 of a turn. A minute of arc is π/10800 of a radian. A second of arc, arcsecond , or arc second is 1/60 of an arcminute, 1/3600 of a degree, 1/1296000 of a turn, and π/648000 of a radian. These units originated in Babylonian astronomy as sexagesimal subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry,...

After a timeout, Carter sank a 3-pointer from the top of the arc. Miller missed a wide open 3-pointer early in the shot clock in the closing minutes but got his own rebound before making a 3 from the corner to extend the lead to 72-57 with 2.33 left.

Junior guard Connor Essegian finally got things going from behind the arc 13 minutes into the contest, pairing two 3-pointers over a 2-minute stretch with a triple from Gary.
In just 26 minutes he hit the milestone, sinking 8-16 of his shots from behind the arc. He is the fourth-youngest player to ever hit the 50-point mark, and did so against fellow FrenchmenBilal Coulibaly and Alexandre Sarr ...Related ... Related ... ....
Thompson mustered an impressive 22 points on 6-12 shooting from behind the arc, and was Dallas' second-leading scorer behind Luka Doncic's 31-point-outing ... In those final minutes, the Warriors made 3-4 shots from behind the arc.
They missed their first 10 attempts beyond the arc to start the game and finished 3-for-24 ... He also added a triple from the top of the arc to knot the score at 52 and lead to a Kansas timeout with less than nine minutes to play.
Against the Tigers, they had that by the first media timeout (7½ minutes in) and led 25-2. They were 8 of 22 behind the 3-point arc in the opener … and made 10 of their first 12 against Oxy ... 13 minutes.

The junior guard played in and started all but one game last year and led UCLA in minutes, points and assists per game ... However, until he makes strides on defense, Cronin is unlikely to give him big minutes in meaningful contests.
American kept up its barrage from beyond the arc out of the break, sinking two more inside the first five minutes of the second half for a 46-43, lead ... He reentered just minutes later, immediately finishing a tough one from in close for a 50-45 lead.
Saint Francis got 11 points from Kelly, and shot the ball well from the outside in the first 20 minutes — going 6-of-15 from beyond the arc, as Ace Talbert and JeremyClayville knocked down two apiece.
