Use the below online Milliradian to Second of arc converter to convert an angle milliradian to second of arc:

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 milliradian to second of arc

A full circle (360°) ≈ 6283 milliradians
Also, 1° = 3600 asec
Therefore 6283/360 milliradians = 3600 asec
Then 1 milliradian = (3600/6283)*360 = 206.27 asec
Thus 1 mrad = 206.27 asec

### Example 1:

Convert 15 milliradian to second of arc
Therefore, 15 mrad = 15 * 206.27 = 3094.05 asec

### Example 2:

Convert 50 milliradian to second of arc
Therefore, 50 mrad = 50 * 206.27 = 10313.5 asec
