Use the below online Radian to Second of arc converter to convert an angle radian to second of arc:
Radian
Radian is a unit of measurement of an angle. Radian of one circle is the length of circumference divided by the radius or 2πr/r or 2π. Therefore a full circle has 2π radians which is equal to 360 degrees. Thus one radian is equal to 180/π degrees.
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 radian to second of arc
1° = 3600 arcsecond
1° = π/180 radians
Therefore π/180 radians = 3600 arcsecond
Then 1 radian = 3600*180/π = 648000/π arcsecond
Thus 1 radian = 206265 arcsecond
Example 1:
Convert 15 radian to second of arc
1 rad = 206265 asec
Therefore, 15 rad = 15 * 206265 = 3093975 asec
Example 2:
Convert 50 radian to second of arc
1 rad = 206265 asec
Therefore, 50 rad = 50 * 206265 = 10313250 asec
