How to Convert Circles to Seconds Of Arc

Protractors are often used to measure angle

To convert a circle measurement to a second of arc measurement, multiply the angle by the conversion ratio. One circle is equal to 1,296,000 seconds of arc, so use this simple formula to convert:

seconds of arc = circles × 1,296,000

The angle in seconds of arc is equal to the circles multiplied by 1,296,000.

For example, here's how to convert 5 circles to seconds of arc using the formula above.

5 cir = (5 × 1,296,000) = 6,480,000"

Circles and seconds of arc are both units used to measure angle. Keep reading to learn more about each unit of measure.

Circles

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.

Seconds 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″.
