Angle Converter
Convert an angle between degrees, radians, gradians, turns, arcminutes, and arcseconds locally in your browser.
Convert an angle between degrees, radians, gradians, turns, arcminutes, and arcseconds. Negative values are valid, for example −90 degrees.
Conversions run locally in your browser; your angle value is not uploaded or stored.
Convert one angle into the units you need.
Enter an angle and choose its unit to see the equivalent degrees, radians, gradians, turns, arcminutes, and arcseconds. Negative values are valid, for example for signed rotations. It runs locally in your browser, so your value is not uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Which angle units can I convert?
Enter an angle in degrees, radians, gradians, turns, arcminutes, or arcseconds. The converter returns the equivalent value in all six units using 180 degrees = PI radians, 200 gradians = 180 degrees, 1 turn = 360 degrees, 1 degree = 60 arcminutes, and 1 arcminute = 60 arcseconds.
Can I convert negative, zero, or decimal angles?
Yes. Negative values are valid for signed rotations, zero is valid, and decimal values are accepted. Results show up to six decimal places when needed.
What happens with very large angles?
The converter shows an error when the entered angle is too large to convert safely, instead of returning an unreliable rounded result.
Does my angle leave my browser?
No. The conversion and copy action run locally in your browser. CodeASystem does not upload or store the value you enter.
