How to Convert Gradians to Seconds Of Arc

Protractors are often used to measure angle

To convert a gradian measurement to a second of arc measurement, multiply the angle by the conversion ratio. One gradian is equal to 3,240 seconds of arc, so use this simple formula to convert:

seconds of arc = gradians × 3,240

The angle in seconds of arc is equal to the gradians multiplied by 3,240.

For example, here's how to convert 5 gradians to seconds of arc using the formula above.
5g = (5 × 3,240) = 16,200"

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

Gradians

A gradian is equal to 1/400 of a revolution or circle, or 9/10°. This unit simplifies the measurements of right angles, as 90° is equal to 100 gradians.

A gradian is sometimes also referred to as a grad, gon, or grade. Gradians can be abbreviated as g, and are also sometimes abbreviated as gr or grd. For example, 1 gradian can be written as 1g, 1 gr, or 1 grd.

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″.
