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.
Gradian
A gradian divides a right angle into 100 parts and a full turn into 400. Surveying equipment still uses gradians in several countries.
