180/60 is 3 degrees
A 180-degree arc is also called a half-circle.
A minor arc.
A major arc
An arc that lies between the sides of a central angle of 180 degrees is known as a semicircle. A central angle of 180 degrees is half of a full circle, so the corresponding arc covers half of the circumference of the circle. In geometric terms, a semicircle is a special case of an arc where the angle subtended by the arc is exactly 180 degrees.
Messier 14 or NGC 6402 has an apparent dimension of 11 minutes of arc.
Just "degree", not "arc degree". A degree has 60 minutes; therefore, to convert from degrees to minutes, you multiply by 60.

It is half the circumference of a circle that has an arc of 180 degrees
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
1 degree = 60 minutes of arc 1/2 o = 60/2 ' = 30'
A circle subtends 360° . Therefore. if the angle subtended at the centre of a circle by an arc is greater than 180° then this is the major arc. By comparison, the minor arc will subtend an angle less than 180°
An arc whose measure is less than 180 degrees is called a Minor Arc.
A 180-degree arc is also called a half-circle.
