Unit Story
Radian
A radian links an angle directly to a circle: the arc length equals the radius. That natural relationship makes radians central to mathematics and engineering.
Arcsecond
An arcsecond is one sixtieth of an arcminute. Astronomers use arcseconds for very small apparent separations in the sky.
