How to Convert Seconds Of Arc to Gradians

Protractors are often used to measure angle

To convert a second of arc measurement to a gradian measurement, multiply the angle by the conversion ratio. One second of arc is equal to 0.000309 gradians, so use this simple formula to convert:

gradians = seconds of arc × 0.000309

The angle in gradians is equal to the seconds of arc multiplied by 0.000309.

For example, here's how to convert 5 seconds of arc to gradians using the formula above.
5" = (5 × 0.000309) = 0.001543g

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

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″.

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.
