About Angle Converter

The Angle Converter is an online tool that converts between 7 types of angle units with degrees as the base unit. It supports radians, gradians, arcminutes, arcseconds, turns, and milliradians.

Radians are essential for trigonometry and programming; gradians are standard in surveying and civil engineering; arcminutes and arcseconds are critical in astronomy and geographic coordinates; milliradians are used for precision measurements in military and engineering.

Supports degrees-minutes-seconds (DMS) format for complex angle notation. Provides instant, accurate conversions across mathematics, physics, engineering, astronomy, surveying, and CAD applications. Real-time conversion enables simultaneous conversion to all supported units.

How to use Angle Converter

  1. Enter the value to convert in the input field (supports decimal, DMS format like 45°30'15", etc.)
  2. Select the source unit from the dropdown: degrees, radians, gradians, arcminutes, arcseconds, turns, or milliradians
  3. Conversion results for all units instantly display in a table as you type
  4. Click any common angle reference below to auto-populate the value and instantly calculate all conversions
