What is Angle Converter?
The Angle Converter is a free online tool that helps you convert values between different units of angle. Convert between degrees, radians, gradians, minutes of arc, seconds of arc, and turns. This tool provides instant, accurate results with support for all major unit conversions in this category.
How the Conversion Works
All angle units convert through radians. Degrees: rad = ° × π/180. Gradians: rad = grad × π/200. Minutes of arc: rad = ' × π/10800. Turns: 1 turn = 2π radians.
How to Use This Converter
Using the Angle Converter is simple:
1. Enter the numeric value you want to convert in the input field
2. Select the unit you are converting from using the first dropdown (available units: Degree (°), Radian (rad), Gradian (grad), Minute of Arc ('), Second of Arc ("), and 1 more)
3. Select the unit you are converting to using the second dropdown
4. Click "Convert" to see the result instantly
5. Use the "Swap" button to quickly reverse the conversion direction
6. View the "All Conversions" table to see the value in every available unit
Example Conversions
Here are some common conversions you can perform with this tool:
1 ° → ? rad, 1 rad → ? °, 1 ° → ? '
Try clicking any of the "Popular Conversions" buttons above to instantly set up these conversions. For example, you can quickly convert between metric and imperial units, which is especially useful when working with international measurements or specifications.
Benefits and Use Cases
Essential for trigonometry, navigation, surveying, robotics, and game development. Used by mathematicians, engineers, surveyors, and game developers.
Common Mistakes to Avoid
Avoid these common pitfalls when using the Angle Converter:
- Confusing degrees with radians (they are very different — 360° = 2π rad)
- Assuming gradians are the same as degrees
- Forgetting to convert between decimal degrees and DMS (degrees, minutes, seconds)
- Mixing up minutes of arc with time minutes
Being aware of these issues will help you get accurate conversions every time.
