FAQ
How do you convert between angle units?
The core approach is to convert all units to radians first, then from radians to the target unit. 1 turn = 2π radians = 360° = 400 gradians = 21,600 arcminutes = 1,296,000 arcseconds.
What is a radian?
A radian is the SI unit for measuring angles. One radian is the angle subtended at the center of a circle by an arc equal in length to the radius. 180° = π radians.
What is a gradian?
A gradian defines a right angle as 100 grad, so a full circle = 400 grad. It's commonly used in surveying and civil engineering.
What are arcminutes and arcseconds used for?
Arcminutes and arcseconds are used in astronomy, navigation, and optics. 1° = 60 arcminutes, 1 arcminute = 60 arcseconds.
