Angle converter
Convert degrees, radians, gradians and turns with an angle diagram. Drag the graph handles to change inputs and explore the result.
Your inputs
The editable example is illustrative. Enter your own dimensions, operating data, prices, and fees. Results update as you edit.
Calculations run in your browser. Inputs are not saved or sent to analytics.
How it works
- Converted value = × f₁ / f₂
- 360° = 2π rad = 400 gon = 1 Turns

Assumptions and limitations
Angles keep their sign and complete turns; values are not reduced modulo one turn. The diagram shows at most one turn, positive counterclockwise. This converts plane angles, not angular velocity. Example: 180° = π rad = 200 gon = 0.5 turns.
