Do you want to convert seconds of arc to revolutions?

## How to Convert Revolutions to Seconds of Arc

To convert a measurement in revolutions to a measurement in seconds of arc, multiply the angle by the following conversion ratio: 1,296,000 seconds of arc/revolution.

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 angle in revolutions multiplied by 1,296,000.

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

## What Is a Revolution?

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.

## 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″.
