What angle units are supported?

Convert between degrees, radians, gradians, arcminutes, arcseconds, turns, and milliradians. All common angular measurement units are included.

How do I convert degrees to radians?

Enter the angle in degrees and the radian equivalent appears instantly. The conversion factor is pi/180, so 180 degrees equals pi radians.

Gradians divide a circle into 400 units instead of 360 degrees. They are used in some surveying and engineering applications. A right angle is 100 gradians.

Are the conversions exact?

Yes. Angle conversions use exact mathematical formulas. Pi is calculated to full double-precision floating-point accuracy.

When would I use milliradians?

Milliradians are used in military, ballistics, and optics. One milliradian subtends approximately one meter at a distance of one kilometer.
