What is an angle converter?
An angle converter helps you convert angular measurements between degrees, radians, gradians, and turns. Degrees are common in everyday geometry, while radians are widely used in math, physics, and programming. This tool updates instantly and runs locally in your browser for fast performance and privacy.
How to use
- Enter an angle value.
- Select the unit you have (e.g., degrees).
- Select the unit you need (e.g., radians).
- Copy the result for your work.
Common use cases
- Programming: convert to radians for trig functions.
- CAD/3D: verify angles across software outputs.
- Navigation and robotics: compare degrees and turns.
FAQ
Why do many programming APIs use radians?
Radian-based math is natural in calculus and trigonometry, so many libraries standardize on radians.
What is a “turn”?
A turn represents a full rotation. 1 turn equals 360 degrees.
Does this support negative angles?
Yes. Negative angles are supported and commonly used to represent clockwise rotation.
