Quickly and accurately convert between angle units online. Our free Angle Converter supports degrees (°), radians (rad), gradians (gon), arcminutes ('), arcseconds (''), and more. Perfect for calculations in geometry, trigonometry, navigation, engineering, or physics. Get instant angle unit conversions with ease.
Our tool supports a wide range of angle units, including Degrees (°), Radians (rad), Gradians (grad or gon), Arcminutes ('), Arcseconds ("), and Turns or Circles.
Our online Angle Converter uses precise, standard mathematical conversion factors based on the defined relationships between angle units (e.g., 360 degrees in a circle, 2π radians in a circle), ensuring high accuracy suitable for mathematical, scientific, and technical applications.
Yes, our Angle Converter is 100% free to use online. There are no costs, subscriptions, or limitations on the number of angle conversions you can perform.
To convert Degrees to Radians, select 'Degrees' as your 'Convert From' unit and 'Radians' as your 'Convert To' unit. Enter the value in Degrees, and the converter will instantly show you the equivalent in Radians. The conversion factor is π/180 (since 180 degrees = π radians).
To convert Radians to Degrees, select 'Radians' as your 'Convert From' unit and 'Degrees' as your 'Convert To' unit. Enter the value in Radians, and the converter will instantly show you the equivalent in Degrees. The conversion factor is 180/π (since π radians = 180 degrees).
The Gradian (grad or gon) is an angular unit where a right angle is divided into 100 gradians. There are 400 gradians in a full circle. Gradians are primarily used in surveying and some areas of engineering in certain countries as part of the metric system, although degrees and radians are more common globally in mathematics and physics.
Convert between a comprehensive range of angle units, including Degrees (°), Radians (rad), Gradians (grad or gon), Arcminutes ('), Arcseconds ("), and full Circles or Turns. Covers units used in mathematics, engineering, surveying, navigation, and astronomy.

An angle is a measure of the rotation between two intersecting lines or planes. It quantifies the amount of turning around a point or axis. Angles are fundamental in geometry, trigonometry, physics, engineering, and various applications involving direction, orientation, and rotation.
The **Degree (°) ** is the most common unit for everyday use, with a circle divided into 360 degrees. Each degree is subdivided into 60 **Arcminutes (')** and each arcminute into 60 **Arcseconds ('')**. The **Radian (rad)** is the standard unit for angular measurement in mathematics and physics; one radian is the angle subtended by an arc whose length is equal to the radius of the circle (a full circle is 2π radians). The **Gradian (grad or gon)** divides a right angle into 100 gradians, with 400 gradians in a circle, sometimes used in surveying.
Accurate angle conversion is crucial for ensuring correctness in mathematical and scientific calculations (especially in trigonometry and calculus, where radians are often required), for compatibility between different measuring instruments or software (which might use different units), and for precision in fields like surveying, navigation, astronomy, and mechanical engineering involving rotation and orientation. Precision prevents significant errors.
Converting between angle units involves applying specific conversion factors based on the fundamental relationships between them. For example, since a full circle is 360 degrees, 2π radians, and 400 gradians, we have conversion factors like 1 degree = π/180 radians, 1 radian = 180/π degrees, 1 gradian = 0.9 degrees, etc. Converting degrees to arcminutes and arcseconds involves factors of 60. Our online converter handles these precise calculations automatically.
Our Angle Converter is highly applicable. Surveyors convert angles between degrees, gradians, and decimal degrees. Navigators use degrees and related units for bearings and positions. Astronomers measure positions and separations of celestial objects in degrees, arcminutes, and arcseconds. Engineers convert rotational angles (often in degrees or radians) for mechanical or electrical system design. It's a versatile tool for anyone working with angular measurements.
Angles less than a degree can be expressed in decimal degrees (e.g., 45.5°) or in Degrees, Minutes, and Seconds (DMS) format (e.g., 45° 30' 0''). One degree equals 60 minutes, and one minute equals 60 seconds. Conversions between DMS and decimal degrees are common. Our converter primarily works with decimal values for input and output but can handle conversions between degrees, arcminutes, and arcseconds.
