Convert angle units in real time โ degrees, radians, gradians, and turns. Useful for trigonometry in programming, technical drawing, or surveying.
How to use
- Enter a value into any angle unit field (degree, radian, gradian, turn, etc.).
- The other unit fields update with the converted value in real time.
- Use the radian value directly in code that expects trig functions like sin/cos to take radians.
FAQ
What is a radian?
A unit of angle based on the ratio of arc length to radius, commonly used in math and programming trig functions (sin, cos, etc.). One radian is about 57.2958 degrees.
How many radians are in 360 degrees?
360 degrees equals 2ฯ (about 6.2832) radians, or one full turn.
Can I use this to get the value to pass into Math.sin()?
Yes โ most programming languages' sin/cos functions expect radians, so converting degrees to radians here gives you the value to use directly.
What is a gradian?
A unit where a right angle equals 100 gradians, sometimes used in surveying. 360 degrees equals 400 gradians.
Can it convert arcminutes and arcseconds too?
Yes โ arcminute and arcsecond units, related to DMS notation, are supported and convert to and from degrees.
