Angle Converter
Convert angles between degrees, radians, gradians, arcminutes, arcseconds, and full turns. Angles are measured differently across math, engineering, surveying, and navigation, and mixing degrees with radians is a classic source of bugs and errors. This converter uses exact relationships, with a full turn equal to 360 degrees, 2 pi radians, or 400 gradians, so the results are precise. It is useful for trigonometry homework, CAD work, rotating parts, and reading survey bearings. Choose the unit you have and the one you want, type a value, and the answer updates live as you type. Because it runs entirely in your browser, the tool is instant, keeps your input private, and continues to work without an internet connection after the first load.
How to use Angle Converter
- Enter an angle in the unit you have.
- Read the equivalent in every other angle unit.
- Copy the converted angle.
Frequently asked questions
Which angle units can I convert?
It converts between degrees, radians, gradians, arcminutes, arcseconds, and full turns.
How many radians are in 180 degrees?
Exactly pi radians, and the tool uses the pi/180 factor to convert degrees to radians precisely.
What is a gradian?
A gradian divides a right angle into 100 units, so a full turn is 400 gradians, and the tool supports it directly.
What is Angle Converter?
Convert angles between degrees, radians, gradians, arcminutes, arcseconds, and full turns. Angles are measured differently across math, engineering, surveying, and navigation, and mixing degrees with radians is a classic source of bugs and errors.
