Use the below online Second of arc to Gradian converter to convert an angle second of arc to gradian:

Gradian, also known as gon, grad or grade is a unit of measurement of an angle in which the angle of an entire circle is 400 gradians. A right angle is therefore 100 gradians. One gradian equals 1/400 of a full circle.

## Second of arc

A Second of arc or arcsecond is a unit of measurement of an angle which is equal to 1/60 of an arcminute or 1/3600 of a degree or π/648000 of a radian. The standard symbol for the arcsecond is the double prime(“) or double quote. Thus One arcsecond is written as 1”. It is also abbreviated as arcsec or asec.

## How to convert second of arc to gradian

A Second of arc = 1/3600 degree
Then, 1° = 3600 arcsec
A full circle (360°) = 400 gradians
Therefore, 3600 arcsec = 400/360 gradians
Then, 1 arcsec = (400/360)/3600 = 0.0003 gradians
Thus 1 arcsec = 0.0003g

### Example 1:

Convert 15 second of arc to gradian
1 arcsec = 0.0003g
Therefore, 15 arcsec = 15 * 0.0003= 0.0045g

### Example 2:

Convert 50 second of arc to gradian
1 arcsec = 0.0003g
Therefore, 50 arcsec = 50 * 0.0003= 0.015g
