What is a Radian?
A radian (rad) is the angle subtended by an arc equal in length to the radius. Radians are the standard angle unit in mathematics and physics.
What is a Arcsecond?
An arcsecond (″) is 1/60 of an arcminute or 1/3600 of a degree. Arcseconds are used in astronomy for star positions and telescope resolution.
