Angle Converter
Convert plane angle among degrees, radians, gradians (gon), turns, and arcminutes.
How to use
- Enter the angle magnitude and choose representations from degree, radian, gon, turn, and arcminute.
Capabilities and scope
Compare systems where a full turn is represented as 360°, 2π rad, 400 gon, or 1 turn.
How it works
Radians are the reference: degree=π/180 rad, gradian=π/200 rad, turn=2π rad, and arcminute=π/10800 rad.
Example
180° = π rad = 200 gon = 0.5 turn.
Useful for
- Switch between degrees and radians for math
- Compare gon in surveying
- Convert arcminutes to degrees
Before you use it
- Angles are not normalized into a canonical range; the entered rotation magnitude is converted as-is.

Frequently asked questions
Will 360° be normalized to 0°?
No. It is converted to 2π rad or 1 turn, preserving the entered magnitude.
