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

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 gradian to second of arc

Therefore 1 degree = 400/360 gradians
Also, 1 degree = 3600 arcsecond
Therefore 400/360 gradians = 3600 arcsecond
Thus 1 gradian = 3600*360/400 = 3240 arcsecond

### Example 1:

Convert 15 gradian to second of arc
1g = 3240 asec
Therefore, 15g = 15 * 3240 = 48600 asec

### Example 2:

Convert 50 gradian to second of arc
Therefore, 50g = 50 * 3240 = 162000 asec
