How to Convert Revolutions to Seconds Of Arc

To convert a revolution measurement to a second of arc measurement, multiply the angle by the conversion ratio.

Since one revolution is equal to 1,296,000 seconds of arc, you can use this simple formula to convert:

seconds of arc = revolutions × 1,296,000

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

For example, here's how to convert 5 revolutions to seconds of arc using the formula above.
5 r = (5 × 1,296,000) = 6,480,000"

How Many Seconds Of Arc Are in a Revolution?

There are 1,296,000 seconds of arc in a revolution, which is why we use this value in the formula above.

1 r = 1,296,000"

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


A revolution, or turn, is equal to 1 rotation around a circle, or 360°. Revolutions are commonly used to measure the speed of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle's engine.

A revolution is sometimes also referred to as a turn, cycle, or complete rotation. Revolutions can be abbreviated as r, and are also sometimes abbreviated as rev or cyc. For example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.

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″.
