Use the below online Second of arc to Milliradian converter to convert an angle second of arc to milliradian:
Milliradian
A Milliradian, often called as mil or mrad is a unit of measurement of an angle which is defined as a thousanth of the radian (0.001 radian), meaning that a full circle of 360 degree equals to 2000π or approximately 6283 milliradians.
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 milliradian
A Second of arc = 1/3600 degree
Then, 1° = 3600 arcsec
A full circle (360°) = 2000π milliradians
Then, 1° = 2000π/360 milliradians
Therefore, 3600 arcsec = 2000π/360 milliradians
Then, 1 arcsec = (2000π/360)/3600 = 0.0048 milliradians
Thus 1 arcsec = 0.0048 mrad
Example 1:
Convert 15 second of arc to milliradian
1 arcsec = 0.0048 mrad
Therefore, 15 arcsec = 15 * 0.0048 = 0.072 mrad
Example 2:
Convert 50 second of arc to milliradian
1 arcsec = 0.0048 mrad
Therefore, 50 arcsec = 50 * 0.0048 = 0.24 mrad
