How to Convert Second to Radian

1 second = 4.84814 × 10-6 radians

Radian = Second × 4.84814 × 10-6

Example: 25" × 4.84814 × 10-6 = 0.0001212 rad

About these units

Second: An arcsecond (second of arc) is 1/60 of an arcminute.It is common in astronomy, surveying, astrometry, and precision optics for high-precision angles.

Radian: The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.Although mathematically dimensionless, th...
