Angle Converter
Convert angles between degrees, radians, arcminutes, arcseconds, grads, mils, and more instantly in the browser.
What Is Angle Converter?
The Angle Converter converts between many common angular units—such as degrees, radians, arcminutes, arcseconds, gradians (gon/grad), mils, turns, and sextants—directly in your browser. Choose a From Unit, enter the angle value, and pick a To Unit.
Key Relationship
Degrees and radians are linked by:
$$\theta_{rad} = \theta_{deg} \times \frac{\pi}{180}$$
How to Use
- Enter the angle in Angle Value.
- Select your unit in From Unit.
- Select your unit in To Unit (or use Swap).
Frequently Asked Questions
Why does swapping matter?
Swap exchanges the From/To units so you can convert the other direction without re-entering everything.
Do gon and grad match?
Yes. In this tool, both represent full-circle divisions where 400 units equal 360 degrees.
What are the different “mil” types?
“mil (Nato)”, “mil (Soviet Union)”, and “mil (Sweden)” each use their own full-circle definition. The converter applies those built-in definitions.
Are you doing the conversion in the browser?
Yes. All computations are client-side, so you don’t upload your angle values to the server.
