To convert a second of arc measurement to a circle measurement, divide the angle by the conversion ratio.
Since one circle is equal to 1,296,000 seconds of arc, you can use this simple formula to convert:
The angle in circles is equal to the seconds of arc divided by 1,296,000.
Seconds of arc and circles are both units used to measure angle. Keep reading to learn more about each unit of measure.
What is a Second of Arc?
The second of arc is a unit of angle equal to 1/60th of one minute of arc or 1/3,600 of one degree.
A second of arc is sometimes also referred to as an arc second or arcsecond. Seconds of arc can be abbreviated as arcsec, and are also sometimes abbreviated as asec. For example, 1 second of arc can be written as 1 arcsec or 1 asec.
The second of arc is most commonly expressed using a double prime (″), though a double quote is often used as well. For example, 1 second of arc is most often written as 1″.

What is a Circle?
A circle is the equivalent of 1 revolution around a circle, or 360°.
A circle is sometimes also referred to as a revolution. Circles can be abbreviated as cir; for example, 1 circle can be written as 1 cir.
A circle is more commonly used to describe a round, symmetrical shape with no corners or edges than it is to describe plane angle. The shape is described by its radius and circumference.
