Angle Converter
Convert angles between degrees, radians, gradians, arcminutes, and revolutions.
How it works
Angles are measured in more units than most people expect. Degrees are everyday, radians rule in math and physics, gradians turn up in surveying, and a full turn is sometimes the cleanest unit of all.
The conversions hinge on a few fixed facts: a full circle is 360 degrees, 2π radians, 400 gradians, or one revolution. From those, every other value follows directly.
Type a value in any unit and the rest fall into place, which saves reaching for π on a calculator every time you need to move between degrees and radians.
Frequently asked questions
How do I use this converter?
Enter a value and choose the unit you are starting from. The tool instantly shows the equivalent in every other angle unit, so there is nothing to submit.
Are the conversions exact?
They use standard published conversion factors, so they are accurate for everyday and technical use. Results are rounded for readability, not because the math is approximate.
Can I convert in either direction?
Yes. Pick any unit as your starting point and read off the others — the conversion works both ways.
