Angle Converter – Convert Between Angle Units
Our Angle Converter is a powerful tool that allows you to convert between different angle measurement units including degrees, radians, gradians, turns, arcminutes, and arcseconds. Whether you're a student, engineer, mathematician, or anyone working with angles, this converter provides accurate results instantly.
What is Angle Conversion?
Angle conversion is the process of changing the measurement of an angle from one unit to another. Different fields use different angle units - mathematics often uses radians, navigation uses degrees, and some engineering applications use gradians.
Supported Angle Units
- Degrees (°): The most common unit, with a full circle being 360°
- Radians (rad): The standard unit in mathematics, with a full circle being 2π radians
- Gradians (grad): Also called gons, with a full circle being 400 gradians
- Turns: Also called revolutions, with one turn being a full circle
- Arcminutes ('): 1/60 of a degree
- Arcseconds ("): 1/60 of an arcminute, or 1/3600 of a degree

Common Angle Conversions
- Degrees to Radians: Multiply by π/180
- Radians to Degrees: Multiply by 180/π
- Degrees to Gradians: Multiply by 10/9
- Gradians to Degrees: Multiply by 0.9
- Degrees to Arcminutes: Multiply by 60
- Arcminutes to Degrees: Divide by 60
Angle Conversion Formulas
The converter uses these fundamental relationships:
- 1 full circle = 360° = 2π radians = 400 gradians = 1 turn
- 1° = 60 arcminutes = 3600 arcseconds
- 1 radian = 180/π degrees ≈ 57.2958°
- 1 gradian = 0.9 degrees
Example Conversion
Converting 45 degrees to radians:
- 45° × (π/180) = π/4 radians ≈ 0.7854 radians
- This is a common angle in trigonometry
Applications of Angle Conversion
- Mathematics: Converting between degrees and radians for trigonometric functions
- Engineering: Working with different measurement systems in technical drawings
- Navigation: Converting between different coordinate systems
- Astronomy: Measuring angular distances between celestial objects
- Surveying: Using different angle units for land measurement
Angle Converter FAQs
1. Why are there different angle measurement systems?
Different systems developed for various practical and mathematical reasons. Degrees are convenient for everyday use, radians are mathematically natural, and gradians are used in some engineering applications.
2. Which angle unit is most accurate?
All units are equally accurate when used properly. The choice depends on the application and convention in your field.
3. Can I convert negative angles?
Yes, the converter handles negative angles, which represent clockwise rotation from the reference direction.
4. What's the difference between arcminutes and minutes of time?
Arcminutes are 1/60 of a degree in angle measurement, while minutes of time are 1/60 of an hour in time measurement.
5. How precise are the conversions?
The conversions are mathematically exact, though displayed results may be rounded for readability.
