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...
